477e3dd8c1 sh/gendepends.sh.in: fix detection of service scripts
We do not need to care about the path on the shebang line of a service
script as long as the shebang line ends with "openrc-run".
This fixes #119 and #120.

e5c2a378f3 Remove all occurances of 'before *' from dependencies
Using wildcards in dependencies causes issues when rc_parallel is set to
yes because it can lead to deadlocks.
All dependencies need to be explicit rather than implicit.

This is the first stage of moving this direction.

3c1a71bd9d init.d/sysfs.in: efivarfs tweaks
Since we check for /sys/firmware/efi/efivars, we do not need to check
for /sys/firmware/efi

Since Failing to mount efivarfs is not critical, we silence the error
message from mount.

This file will contain a list of notable changes for each release. Note
the information in this file is in reverse order.
## OpenRC 0.33
This version removes the "service" binary which was just a copy of
"rc-service" provided for compatibility.
If you still need the "service" binary, as opposed to "rc-service", it is
recommended that you use something like Debian's init-system-helpers.
Otherwise, just use "rc-service" in place of "service".
## OpenRC 0.31
This version adds support for Control Groups version 2, which is
considered stable as of Linux-4.13. Please see /etc/rc.conf for
documentation on how to configure control groups.
## OpenRC-0.28
This version mounts efivars read only due to concerns about changes in
this file system making systems unbootable. If you need to change something
in this path, you will need to re-mount it read-write, make the change
and re-mount it read-only.
Also, you can override this behavior by adding a line for efivars to
fstab if you want efivars mounted read-write.
For more information on this issue, see the following url:
https://github.com/openrc/openrc/issues/134
## OpenRC-0.25
This version contains an OpenRC-specific implementation of init for
Linux which can be used in place of sysvinit or any other init process.
For information on its usage, see the man pages for openrc-init (8) and
openrc-shutdown (8).
## OpenRC-0.24.1

# ulimit and CGroups
Setting `ulimit` and `nice` values per service can be done through the
`rc_ulimit` variable.
Setting `ulimit` and `nice` values per service can be done through the `rc_ulimit`
variable.
Under Linux, OpenRC can use cgroups for process management as well. Once
the kernel is configured appropriately, the `rc_cgroup_mode` setting in
/etc/rc.conf should be used to control whether cgroups version one,,
two, or both are used. The default is to use both if they are available.
By changing certain settings in the service's `conf.d` file limits can be
enforced per service. These settings are documented in detail in the
default /etc/rc.conf under `LINUX CGROUPS RESOURCE MANAGEMENT`.
# Dealing with Orphaned Processes
It is possible to get into a state where there are orphaned processes
running which were part of a service. For example, if you are monitoring
a service with supervise-daemon and supervise-daemon dies for an unknown
reason. The way to deal with this will be different for each system.
On Linux systems with cgroups enabled, the cgroup_cleanup command is
added to all services. You can run it manually, when the service is
stopped, by using:
```
# rc-service someservice cgroup_cleanup
```
The `rc_cgroup_cleanup` setting can be changed to yes to make this
happen automatically when the service is stopped.
Under Linux, OpenRC can optionally use CGroups for process management.
By default each service script's processes are migrated to their own CGroup.
By changing certain values in the `conf.d` file limits can be enforced per
service. It is easy to find orphan processes of a service that persist after
`stop()`, but by default these will NOT be terminated.
To change this add `rc_cgroup_cleanup="yes"` in the `conf.d` files for services
where you desire this functionality.

.Sh NAME
.Nm openrc-init
.Nd the parent of all processes
.Sh SYNOPSIS
.Nm
.Sh DESCRIPTION
.Nm
is an init process which can be an alternative to sysvinit or any other
init process.
.Pp
To use
.Nm
configure your boot loader to invoke it or symlink it to /sbin/init.
Also, you will need to use
.Xr openrc-shutdown 8 ,
to halt, reboot or poweroff the system.
.Pp
The default runlevel is read from the init command line, the
rc_default_runlevel setting in rc.conf, the kernel command line, or it is
assumed to be "default" if it is not set in any of these places.
.Pp
.Nm
doesn't manage getty's directly, so you will need to manage them another
way. For example, you can use the agetty service script as described in
agetty-guide.md in this distribution.
.Sh BUGS
This was first released as part of OpenRC 0.25.
I do not know of any specific issues. However, since this is the first
release of openrc-init, please test and report any issues you find.

These functions should be used to perform preparation before the

exists, is the right type and has the correct owner and access modes. If
any of these tests fail, the path is created and set up as specified. If
more than one of -d, -f or -p are specified, the last one will be used.
.Pp
The argument to -m is a three or four digit octal number. If this option
is not provided, the value defaults to 0644 for files and 0775 for
directories.
.Pp
The argument to -o is a representation of the user and/or group which
should own the path. The user and group can be represented numerically
or with names, and are separated by a colon.
.Pp
The truncate options (-D and -F) cause the directory or file to be
cleared of all contents.
.Pp
If -W is specified, checkpath checks to see if the first path given on
the command line is writable. This is different from how the test
command in the shell works, because it also checks to make sure the file
system is not read only.

.Sh NOTE
If respawn-delay, respawn-max and respawn-period are not set correctly,
it is possible to trigger a situation in which the supervisor will
infinitely try to respawn a daemon. To avoid this, if you change the
values of --respawn-delay, --respawn-max or --respawn-period, always
make sure the settings mmake sense. For example, a respawn period of 5
seconds with a respawn max of 10 and a respawn delay of 1 second leads
to infinite respawning since there can never be 10 respawns within 5
seconds.
