Provide a more prominent alert to the user if an overlay is
missing or the overlay module is not available and a temporary
overlay will be provided. This, to avoid losing data intended to
persist.
Integrate the option to use an OverlayFS as the root filesystem
into the 90dmsquash-live module for testing purposes.
The rd.live.overlay.overlayfs option allows one to request an
OverlayFS overlay. If a persistent overlay is detected at the
standard LiveOS path, the overlay & type detected will be used.
Tested primarily with transient, in-RAM overlay boots on vfat-
formatted Live USB devices, with persistent overlay directories
on ext4-formatted Live USB devices, and with embedded, persistent
overlay directories on vfat-formatted devices. (Persistent overlay
directories on a vfat-formatted device must be in an embedded
filesystem that supports the creation of trusted.* extended
attributes, and must provide valid d_type in readdir responses.)
The rd.live.overlay.readonly option, which allows a persistent
overlayfs to be mounted read only through a higher level transient
overlay directory, has been implemented through the multiple lower
layers feature of OverlayFS.
The default transient DM overlay size has been adjusted up to 32 GiB.
This change supports comparison of transient Device-mapper vs.
transient OverlayFS overlay performance. A transient DM overlay
is a sparse file in memory, so this setting does not consume more
RAM for legacy applications. It does permit a user to use all of
the available root filesystem storage, and fails gently when it is
consumed, as the available free root filesystem storage on a typical
LiveOS build is only a few GiB. Thus, when booted on other-
than-small RAM systems, the transient DM overlay should not overflow.
OverlayFS offers the potential to use all of the available free RAM
or all of the available free disc storage (on non-vfat-devices)
in its overlay, even beyond the root filesystem available space,
because the OverlayFS root filesystem is a union of directories on
two different partitions.
This patch also cleans up some message spew at shutdown, shortens
the execution path in a couple of places, and uses persistent
DM targets where required.
Documentation is updated for these changes.

The default output filename for --uefi is
<EFI>/EFI/Linux/linux-$kernel$-<MACHINE_ID>-<BUILD_ID>.efi.
<EFI> might be /efi, /boot or /boot/efi depending on where the ESP partition
is mounted. The <BUILD_ID> is taken from BUILD_ID in /usr/lib/os-release or
if it exists /etc/os-release and is left out, if BUILD_ID is non-existant or
empty.
Also a new option --no-machineid was added, which affects the default output
filename of --uefi and will discard the <MACHINE_ID> part.
Some docs claimed that values in certain config files would be
overwritten, when they would actually be overridden.
Override: a file is not modified but its contents are superseded by
something else. (configurations set in
/etc/dracut.conf.d/*.conf override configurations set in
/etc/dracut.conf)
Overwrite: a file is modified or its contents replaced by an action
(use dracut --force to overwrite the existing initramfs)
For example under x86, someone maybe missunderstand that the vmlinuz
is the link /boot/vmlinuz points to a specific kernel image and use
the following command directly.
mkinitrd -k vmlinuz

Now dracut only attempts to copy GlobalKnownHostsFile while generating kdump's
initramfs. This method will cause kdump's failure if users set customized
UserKnownHostsFile in /etc/ssh/ssh_config. This patch simply attempts to copy
those files too while going through /etc/ssh/ssh_config. Note that we need to
make sure ~/foo will be copied as /root/foo in kdump's initramfs.

The current method for memory debug is to use "rd.memdebug=[0-3]",
it is not enough for debugging kernel modules. For example, when we
want to find out which kernel module consumes a large amount of memory,
"rd.memdebug=[0-3]" won't help too much.
A better way is needed to achieve this requirement, this is useful for
kdump OOM debugging.
The principle of this patch is to use kernel trace to track slab and
buddy allocation calls during kernel module loading(module_init), thus
we can analyze all the trace data and get the total memory consumption.
As for large slab allocation, it will probably fall into buddy allocation,
thus tracing "mm_page_alloc" alone should be enough for the purpose(this
saves quite some trace buffer memory, also large free is quite unlikey
during module loading, we neglect those memory free events).
The trace events include memory calls under "tracing/events/":
kmem/mm_page_alloc
We also inpect the following events to detect the module loading:
module/module_load
module/module_put
Since we use filters to trace events, the final trace data size won't
be too big. Users can adjust the trace buffer size via "trace_buf_size"
kernel boot command line as needed.
We can get the module name and task pid from "module_load" event which
also mark the beginning of the loading, and module_put called by the
same task pid implies the end of the loading. So the memory events
recorded in between by the same task pid are consumed by this module
during loading(i.e. modprobe or module_init()).
With these information, we can record the rough total memory(the larger,
the more precise the result will be) consumption involved by each kernel
module loading.
Thus we introduce this shell script to find out which kernel module
consumes a large amount of memory during loading. Use "rd.memdebug=4"
as the tigger.
After applying this patch and specifying "rd.memdebug=4", during booting
it will print out something extra like below:
0 pages consumed by "pata_acpi"
0 pages consumed by "ata_generic"
1 pages consumed by "drm"
0 pages consumed by "ttm"
0 pages consumed by "drm_kms_helper"
835 pages consumed by "qxl"
0 pages consumed by "mii"
6 pages consumed by "8139cp"
0 pages consumed by "virtio"
0 pages consumed by "virtio_ring"
9 pages consumed by "virtio_pci"
1 pages consumed by "8139too"
0 pages consumed by "serio_raw"
0 pages consumed by "crc32c_intel"
199 pages consumed by "virtio_console"
0 pages consumed by "libcrc32c"
9 pages consumed by "xfs"
From the print, we see clearly that "qxl" consumed the most memory.

Some crashkernel targets still use legacy NTLM auth, which
require those (bsc#869496). This patch enumerates all dependent
hash algorithems, because even though most of them are probably
compiled in, older ones (e.g. md4 and arc4) usually aren't.
Contrary to previous intel pinctrl drivers, the cherryview driver can be
and usually is built as a module. However, it sets up the SDIO pinout
so sdhci can make use of the SD card reader, which may subsequently
hold a root file system on a card (bsc#998440).
Also change <= N to < N+1. For example, dracut-029-1 > dracut-029, so would not
get obsoleted properly. This all applies to old versions, so doesn't make much
difference in practice, so just fix it to avoid c&p duplication of the bad
pattern in the future.

If emergency and shutdown-emergency hooks are called, the systemd should
poweroff the testsuite, therefore "rd.shell=0" is given on the test

"rd.shell=0" has to be parsed correctly by the test suite real root init

Both 'utmp' and 'root' groups are mentioned in tmpfiles.d/systemd.conf

It's probably better to have something equiv to inst_rule_group_owner()
for udev rules which parses out users and groups and adds them to the
passwd/group db respectively.
Could also rely on sysusers but as the initramfs is static in this
sense, it's more efficient to pre-define the users IMO.

I met a problem when passing kdump dns to dracut via "nameserver=x.x.x.x",
the dns I provided didn't appear in the "/etc/resolv.conf".
After some debugging, found that when setup dhcp DNS, in setup_interface()
and setup_interface6(), it has:
echo "search $search $domain" > /tmp/net.$netif.resolv.conf
So if "$search $domain" isn't NULL(this is ture in my kdump environment),
the dns contents(that is, dns1, dns2, nameserver) in "ifup" before dhcp
will be discarded.
This patch addresses it by handling dhcp first. In fact this is also the

Recently following patches have been added in upstream Linux kernel, which
(1) fixes parent of watchdog_device so that
/sys/class/watchdog/watchdogn/device is populated. (2) adds some sysfs
device attributes so that different watchdog status can be read.
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6551881c86c791237a3bebf11eb3bd70b60ea782http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=906d7a5cfeda508e7361f021605579a00cd82815http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=33b711269ade3f6bc9d9d15e4343e6fa922d999b
With the above support, now we can find out whether a watchdog is active or
not. We can also find out the driver/module responsible for that watchdog
device.
Proposed patch uses above support and then adds module of active watchdog
in initramfs generated by dracut for hostonly mode. Kernel module for
inactive watchdog will be added as well for none hostonly mode.
When an user does not want to add kernel module, then one should exclude
complete dracut watchdog module with --omit.

By default, dracut only builds in dm-service-time into the initramfs as
that is the default multipath.conf path selector. If the user changes
the path selector to "round robin" on the fly and runs dracut, multipath
does not find any paths on boot and the user will be dropped into a
shell.
Apparently, in RHEL7 dracut defaults to "hostonly" mode, i.e. modules
not currently in use at the time dracut runs do not get built into
initramfs. This is definitely one case where this doesn't work. A change
to reconfigure multipath probably should not render the system

Once lvm2 starts using /run (bug 742554), it should be no longer
necessary to disable file-based locking in the vgchange call in
fedora-storage-init.
Removing '--sysinit' will make it safe to call LVM operations
concurrently from other units.
The --sysinit is a compound option consisting of:
-> --ignorelockingfailure - not needed anymore, the /run/lock/lvm is
available rw soon in boot process
-> --ignoremonitoring - not needed since /run is available, this would
require the dm-event.service to be run before
fedora-storage-init.service (and new lvm2-activation.service when
deployed). But that's a one line change - I'll have a look whether it
plays well with other services and if yes, I'll commit the change. N.B.:
This has a consequence that all volumes activated on vgchange -ay will
be monitored at the same time they're activated (which is a plus I
think). The lvm2-monitor will just grab all the other volumes not
activated at the time of the boot's vgchange -ay call. But that's not an
issue (for already monitored volumes, calling vgchange --monitor y will
just be a NOOP).
-> --poll n - not needed, we can run the polldaemon as the /run is
available and rw (in case there's unfinished merge or mirror sync from
previous system run, the poll-daemon will be triggered at boot now).
Actually, the polldaemon should be triggered as a service like dmeventd
is, not forked off from the LVM command itself, like from vgchange in
this case - we still need to change this - there's a bug open for this
request already (bug #814857). However, we don't have this feature ready
yet so I need to check whether this is OK with the early boot process
with the current state.
Transient snapshots can take advantage of smaller,
non-persistent metadata structures.

On systemd, SIGPIPE is ignored by default; see man 5 systemd.exec for
IgnoreSIGPIPE=. As a result, lsinitrd.sh under a systemd service
outputs "cat: write error: Broken pipe" in the processing of
determining a compression format of a given initramfs file using cat
command in the write part of a pipeline processing.

kdump.service builds and loads an initramfs for kdump kernel using
kdumpctl command which uses dracut command and so lsinitrd command,
too.
Although there's no actual harm except for the error message, there
has been several inquiries from customers about this message so
far. We should suppress this message to reduce needless
communications.
To suppress the message, this commit cleans up the processing of
reading the first 6 bytes of a given initramfs file without cat
command.

parse-cmdline sets up an initial initiator-name to let iscsid start.
iscsid is started before doing any iscsistart business.
iscsistart is done with systemd-run asynchrone to do things in
paralllel. Also restarted for every new interface which shows up.
If rd.iscsi.waitnet (default) is set, iscsistart is done only
after all interfaces are up.
If not all interfaces are up and rd.iscsi.testroute (default) is set,
the route to a iscsi target IP is checked and skipped, if there is none.
If all things fail, we issue a "dummy" interface iscsiroot to retry
everything in the initqueue/timeout.

If the directory where the .img file is saved has no enough space, or in
other wrong conditions, dracut will get an incomplete file xxx.img. But
sometimes this .img file will be loaded when rebooting the system. And then
some bugs will happen because this .img file is wrong.
So I think dracut should remove the incomplete file because this .img file
with problems was made by dracut. And then the wrong file will not be loaded
anymore.

When systemd's crypttab generator parsed crypttab, it tells
systemd about several devices which may not appear until later
in the boot sequence, and which are not needed while dract is running.
This can particularly happen when an md array is encrypted,
and the array is newly degraded so that it doesn't appear until
dracut runs mdraid_start.sh.
This can result in systemd printing warning messages which are
inappropriate.
So tell systemd that the timeout for each of these is zero.
This is involves splitting some functionality out of wait_for_dev()
That function does two things:
- creates 'finished' hooks so that dracut will wait for the device,
and
- sets the systemd timeout for the device to zero, so systemd doesn't
wait.
We only want the second of these for most encrypted devices.
So split that out into a new function set_systemd_timeout_for_dev(),
and call it from parse-crypt.sh

dracut: Make host only mode more resilient to missing swaps.
This patch set allows swap devices to disappear without cocking up a
host-only initramfs boot.
There is a bug that kdump-initrd contains entry requesting nfs dump
filesystem to get filesystemchecked. And there is an erro message said
that nfs need be checked. But there's no fsck for nfs utility, e.g
fsck.nfs like other file system. Whatever fs_passno 0 or 2 are passed,
no fsck is executed at all for nfs mount.But in dracut, set it to be 2
always, so the erro message appear and it should be set to 0.
In the fstab,the sixth variable fs_passno stands for that the device need
checked or not,and dracut set it to "2".To fix this issue, it should
be "0" when the device is nfs.The third variable stands for the type of
the filesystem and we can use it to judge whether the device is nfs.
So when the third variable of fstab contains "nfs", the sixth variable
fs_passno should be set to "0".

Although various bits are in place to cancel waiting for the /dev/resume
device (actually a symlink), we don't actually ever wait for it.
Also as the udev rule may create the symlink, silence any errors from
our manual ln -s call from the settled job.
The only reason we add swap devices to host-only mode (added in
dd5875499e) is to allow us to process
resume= arguments passed on the kernel command line when the swap
partition lives on something slightly more complex than a normal
partion (e.g. in an LVM or RAID setup).
By adding the device to host_devs, the necessary LVM and RAID hooks
are added and thus the underlying storage will be initialised OK, and
the 95resume module handles the waiting for the device (via udev rules
creating the /dev/resume symlink).
So ultimately, we do not need to hard-code the waiting for the swap
devices into the initramfs at build time as the waiting part can be
dynamic.
This makes things more resiliant to swap partitions disappearing and
being reformatted etc.
Inspired by a patch by Martin Whitaker on Mageia bug:
https://bugs.mageia.org/show_bug.cgi?id=12305
If crypt-lib.sh is sourced from any #!/bin/sh script, a POSIX shell
quirk is in effect that causes variable assignments to "special
builtins" (such as "shift") to leak to their context. So the buggy
code works even despite the missing semicolons.
But if it is sourced by "bash acting under its own name", i.e. from
any #!/bin/bash script, the quirk is disabled, tty_cmd/tty_prompt are
undefined, and ask_for_password doesn't do anything if plymouth is not
present.
AMD's HSA Linux kernel driver (amdkfd) has been merged into the mainline
kernel since kernel 3.19.
However, for the driver to work, it needs to be included in the default
initramfs image, together with the amd_iommu_v2 driver.
The radeon driver (AMD's kernel graphic driver) calls amdkfd during its
initialization and probing stages. Because radeon is included in the
initramfs image, it tries to initialize amdkfd during the early boot
stages. However, as amdkfd is not present there, it fails.
That doesn't harm radeon operation. However, it disables the HSA
abilities in the machine.
Because of the current design, if you later try to "modprobe amdkfd",
you won't be able to run HSA applications, even though the driver will
be loaded.

When 'systemctl daemon-reload' is run, systemd will clean out
/run/systemd/generator and re-run all the generators.
So it is important that the generators always create the required
files.
rootfs-generator.sh currently does *not* create the desired files
if $hookdir/initqueue/finished/devexists-${_name}.sh
exists.
This is not removed by "systectl daemon-reload" so the first time this
generator is run it will do the right thing. Subsequent times it
won't.
This results in incorrect timeouts after "daemon-reload" is run.
So let the existence of each file only guard the creation that file.

A number of timeout scripts can be registered. If any one of them
makes progress - e.g. assembles a degraded md array - then
the main loop should wait a bit longer rather than pressing forward.
This is particularly important is resume-from-hibernate requires a
degraded md array. Both the script to forcibly assemble the md array
and the script to abort hibernation if the device doesn't appear
are 'timeout' scripts. There needs to be a reasonable delay between
these running.
So: if any script has indicated that progress was made, break of out
the loop and go back to normal waiting.

mdraid_start is a number of scripts which run after a timeout.

When current dracut receives an ip with netmask of 255.255.255.255 via DHCP,
setting the also supplied default gateway fails (because it is obviously not
within the netmask).
The setup with a netmask of /32 is quite common in colocation datacenters
where you don't want the machines of two different customers to directly talk
to each other. At least two of the biggest colocation providers in Germany
(1&1 and Strato) do it that way. NetworkManager supports this kind of setup
and the dhclient-scripts of several distributions too.
In this patch I have implemented a simple approach very similar to what is
found in Debian. The dhclient-script from Fedora uses a more sophisticated
approach, but that relies on the ipcalc utility which would introduce a
dependency on Fedora-initscripts for dracut.

When the 'loop' kernel module isn't loaded in a running system, it gets
excluded from the hostonly initrd. Given that the crypt-loop dracut
module has to be loaded explicitly anyway, it makes sense to always
include the requisite loop kernel module.
When booting with 'rd.info', the 'info' statements in the crypt-loop
module's 'loop_decrypt' function are output to stdout along with the key
that gets piped into the 'cryptsetup' command, which causes the crypt
device unlocking to fail.
There are two possible simple solutions to this problem:
1. Redirect the info messages to stderr (just add '>&2' at the end of
the info statements).
or
2. Remove the info statements altogether.
I have tested both and they both work, but this commit implements #2.
The existing info messages are long (they overflow 80 characters
easily) and redundant (the password prompt clearly indicates what is
happening), and just generally not useful. Given that no one has
reported or fixed this bug in the three years that this module has
existed, no one will miss these info messages.
The commit also changes an error message in the same function to be more
descriptive.
With an EFI stub, the kernel, the initramfs and a kernel cmdline can be
glued together to a single UEFI executable, which can be booted by a
UEFI BIOS.
Basic systemd functionality is in 00systemd now.
Switching root and the initrd.target is in 00systemd-initrd.

Previously rd.live.fsimg only supported filesystems residing in
(compressed) archives.
Now rd.live.fsimg can also be used when a squashfs image is used.
This is achieved by extracting the rootfs image from the squashfs and
then continue with the default routines for rd.live.fsimg.
In addition some code duplication got removed and some documentation
got added.

Dracut will generate systemd units for additional devices that should be
brought up during boot, e.g. swap devices. These unit files are broken
symlinks with \ in the filename, e.g.
/etc/systemd/system/initrd.target.wants/dev-disk-by\x2duuid-e6a54f99\x2da4fd\x2d4931\x2da956\x2d1c642bcfee5e.device.
Both the backslash and the broken symlink causes problems for shell
scripts, [ -e "$file" ] isn't enough and read requires the additional -r
argument to not react on the \.
The function 99shutdown/shutdown.sh:_check_shutdown() assumes that
shutdown scripts report success or failure via their return value.
However, "dmsetup remove_all" always reports success, even if some
of the device mappings could not be removed.
I submitted a patch for dmsetup but the lvm2 folks rejected it,
asserting that its behaviour is correct, that "remove_all" should
only be used by developers and that the proper solution would be
to invoke "dmsetup remove" on each device. This does report success
or failure via the return value.
Apart from fixing that issue, this commit also adds the dmsetup
option "--noudevsync". Without it, dmsetup would hang after removal
of a device while trying to communicate with systemd-udevd, which
is no longer running at this shutdown stage.

The sdhci-pci module is currently not being included in the initramfs,
even though other sdhci modules are. This breaks boot on systems that
rely on this driver to access the root filesystem.
Instead of looking for modules that use sdhci_pltfm_init, look for
sdhci_add_host. I checked 3.18 kernel sources, and this change
does not remove any of the previously-matched SDHCI drivers.
It should result in the addition of sdhci-pci, sdhci-s3c, sdhci-spear
and sdhci-acpi.
For targets with colons in the iSCSI target name:
"iqn.2000-09.com.foo:storage-system.e2000:00000001cm1p1"

iscsi_netdev_name.
This patch reintroduces the old IQN, EUI and NAA parsing and enhances
the fallback parser by checking the LUN for a numerical value.

The space does not separate the elements reliably, spaces can be
embedded in parenthesized expressions too:
libgmpxx.so.4 (libc6, hwcap: 0x0000000004000000) => /lib/sse2/libgmpxx.so.4
libgmp.so.10 (libc6, hwcap: 0x0000000004000000) => /lib/sse2/libgmp.so.10
This results in dracut creating '0x0000000004000000' and '=>'
directories in the initramfs image.
When reading the --include part of the script, we had the following
issues to make the code easy to read:
- src & tgt were extract for the original options
- i variable was a file or a directory from src
- s variable was the directory name in case $i was a directory
"s" sounds very close to "src" while "s" is on the "tgt" side. Very
confusing.
"s" was defined before the "if it's a directory" statement while it's
only used inside the "if".
"i" was commit from the "src" but wasn't really explicit.
Having some lines mixing "i" and "s" takes a little time to get read
properly.
This patch offer the following changes:
- "i" is renamed to "objectname" as we don't know if its a file or a
directory
- "s" is renamed to "object_destdir" as the object name becomes a
directory on the destdir
- "object_destdir" (former "s") is moved inside the "if" statement as it's
only used here
- tgt is finally renamed to "target" to be more explicit. We are not all
native english ;o)
My 2 (semantic) cents,
When including a directory, the files were considered in the directory
name which lead to messages like :
cp: failed to access '/var/tmp/initramfs.L9s2zO///init-func': No such file or directory
This patch does make the destdir more explicit and copy files into the
destination directory instead of destdir/filename/

bnx2i is using a separate iSCSI offload engine with a separate
MAC address. As a result, the iBFT information is displaying
a MAC address which does not relate to any MAC address from
the network interfaces.
In addition, the iSCSI offload engine works independently on
the NIC, so we do not need to enable the NIC for iSCSI offload
to work.
This patch modifies the automatic iBFT detection to not set
the 'ip=ibft' flag when bnx2i offload is detected.

However this appraoch is slightly different:
"$netroot" instead of "'$netroot'", etc.
initqueue will process the arguments, assuming the first non-option

udevd will these days default to 'info' logging and thus will
often print out the 'starting version nnn' message (which is
logged at level 'info'), thus spamming the console, even on
'quiet' boots.
We generally expect a udev log level of err (the old default
from pre-October 2013) so we should set that explicilty before
launching udevd in order to suppress the spurious 'info' message.
As we are using the environment variable approach anyway, we
may as well use this method rather than setting the log level
later via udevadm control commands when rd.udev.info/debug are
given on the kernel command line.
The enviroment variable has been around since udev 6b493a20e1
around 2005 so should be safe to use in all cases without version
checks.

Up until now, _check_shutdown() returns true if at least one of
the shutdown hooks succeeded. Change this to only return true if
*all* succeeded. To prevent an infinite loop, introduce an upper
bound of 40 iterations.
When you define the gateway for an interface, dracut sets it up with:
ip route add default via $gw dev $netif
If a default route is already set (e.g. if you have multiple NICs), this
will fail with the message "RTNETLINK answers: File exists".
So, if your first NIC isn't usable as a default route
Using "ip route replace default" instead allows ifup/dhclient-script to
correctly change the default route to the new interface.
loginstall specifies a directory, in which dracut-install records all
files, which were installed from the host system to the initramfs.
Use case is e.g. to create a list of packages to watch for updates, to
maybe trigger a recreation of the initramfs.
Which will not only add listed drivers, but also enforce that they are
tried to be loaded at early boot time.
This is needed if drivers which are not autoloaded (e.g. loop and a lot
others) shall get loaded via initramfs.
Otherwise dracut-logger.sh outputs an empty version on journal testing.

This patch adds bittorrent support to 45url-lib for those that might want
to retrieve the same live image for multiple systems at once without
saturating the network.
This patch requires ctorrent to be installed into initramfs.
Torrent kernel command line format:
root=live:torrent://example.com/liveboot.img.torrent
Start a tracker:
bttrack --bind <tracker_ip> --port 6969 --dfile dstate --reannounce_interval 60
Create the torrent:
ctorrent -t live_image -u http://<tracker_ip>:6969/announce -s live_image.torrent
Seed the initial torrent:
ctorrent live_image.torrent
Boot the live image.
A user can provide a filesystem image (rootfs.img) inside a compressed
tarball and that filesystem image will be mounted read/write. This provides
some benefits over a device mapper snapshot overlay, especially when the
live system becomes full. The boot command line simple needs
"rd.writable.fsimg" added to utilize this feature.
Additional documentation for this option as well as other live boot
options is included.

With the same source of files, it should be possible to generate the

DRACUT_PATH can now be used to specify the PATH used by dracut
to search for binaries instead of the default
/usr/sbin:/sbin:/usr/bin:/bin
This should be set in the distribution config file
/usr/lib/dracut/dracut.conf.d/01-dist.conf
because some inst*() functions check the existance of the source files
and do not know about the "-H" option, some failed to install the
hostonly files.
When installing OS to a VLAN enabled iscsi LUN (extracted from iBFT), "/tmp/net.{xyz}.has_ibft_config" is not being set properly.
Then anaconda installer requires 'BOOTPROTO="ibft"' populated in ifcfg of the vlan interface (ex: ibft0.20), for it to properly populate the kernel parameters post installation. The setting 'BOOTPROTO="ibft"' is populated by write-ifcfg.sh script only if the corresponding interface has a file /tmp/net.{xyz}.has_inft_config
To get around this issue, in ibft_to_cmdline() function in net-lib.sh file, I made the following changes to populate the has_ibft_config file for the vlan interface(ex: ibft0.20):
inst* functions and dracut-install now accept the "-H" flag, which
logs all installed files to /lib/dracut/hostonly-files. This is used
to remove those files, if rd.hostonly is given on the kernel command line.
This patch adds option "-m|--mod" to lsinitrd to list dracut
modules in the image because sometimes having an option to
only list the dracut modules in the image could be handy.

lsinitrd (and hence dracut) currently fail to list the contents of any
LZO-compressed image, and merely spit out misleading xzcat errors.
I guess no-one actually uses them.
rd.iscsi.ibft[=1] should be used instead.
Thing is, 'ip=ibft' is not really an ip setting, but rather a marker
that iBFT should be evaluated.
Also removed the trigger of the warning:
"Warning: Please supply bootdev argument for multiple ip= lines"
When a bonded interface is brought up, any slaves included in the bond
have their hardware address set to that of the bond master. Although
this allows an interface to be brought up on start up, when the
configuration file is imported into the booted system it prevents
the bonded interface being successfully restarted.
The fix involves obtaining the hardware address of the slaves before
they are added to the bond and then using this value in the
configuration file.
Currently the block driver detection for generic initrd doesn't include
the SD/MMC drivers so we fail to boot generic images on any device using
those platforms as boot devices when using a generic initrd. Add logic
to detect those modules. This primarily fixes embedded ARM devices but
also likely intel tablets/dev boards and enterprise hypervisors that
have the ability to boot from SD.
Also the ahci_init_controller misses a number of drivers that use the
libahci_platform module for the init so this fixes some missing achi
moduless too.
Finally it cleans up the ARM storage module hacks that the above now
deals with in a more generic manner.

By convention, strstr should be a literal string match. Previously, it
would match as a glob pattern. Some code used that, so add new
functions strglob and strglobin to do what that code expects, and
specify them tightly too. strglob tests whether the glob pattern
matches the entire string (the name strglob is also used in the yorick
language, and that's what it does there), while strglobin tests whether
the glob pattern matches anywhere in the string.
Also tightens str_starts, str_ends, and str_replace to deal with
literal strings only. In a quick grep I did not find code that depended
on these functions matching globs.
Changes the call sites where strstr was used with glob patterns to use
strglobin or strglob as the intention seemed to be (or, in one case,
strstr with the * removed as it did not affect the result anyway).

Before modifying 69-dm-lvm-metad.rules, we should check for the
existance first. Otherwise this results in error messages on
distributions (debian), which do not ship these rules.
If using systemd in initramfs, we could run into a race condition when
dracut and systemd both are trying to mount and run fsck for the same
filesystem, and mount or fsck could be a failure.
To fix such failure, we should use systemd to mount/fsck from /etc/fstab
only.

This is because bash wants /dev/fd/<num> for constructs like:
foo < <$(bar)
It's useful for passing a full fstab line including like fs_passno so fsck
can take effect.
Previously it's assumed that there's no fs_freq and fs_passno in fstab lines
so original code just append "0 0" at the end of each fstab lines.
Improve this issue by assign default value in case they are not passed in.

This caused the root_dev variable not to be set which in turn meant that
the root device was not whitelisted in 99base/module-setup.sh when injecting
compile-time devexists hooks in hostonly initrds. This ties the generated
initrd to the root fs device (typically the UUID) rather than relying solely
only the root= kernel command line.
While it is hostonly, not hardcoding e.g. UUIDs is still desirable. Any
swap partition on the host device is still added however.
The variable that dhclient sets doesn't have dhcp in the name. This
could cause problems with setups where the server is not the same as the
dhcp server.
Add new functions require_binaries() and require_any_binary() to be used
in the check() section of module-setup.sh.
These functions print a warning line telling the user, which binary is
missing for the specific dracut module.
This unifies the way of checking for binaries and makes the life of an
initramfs creator easier, if he wants to find out why a specific dracut
module is not included in the initramfs.
If the root user generates the initramfs image, preserve the ownership
of the files. This of course cannot be done for non-root users
generating an initramfs image.
Libcurl has wider capabilities than those assigned to it by Dracut.
In this patch to url-lib I've added registration for TFTP URLs,
which I've found to be useful.
