-# OpenRC NEWS
+OpenRC NEWS
+===========
 
 This file will contain a list of notable changes for each release. Note
 the information in this file is in reverse order.
 
+## OpenRC 0.35
+
+In this version, the cgroups mounting logic has been moved from the
+sysfs service to the cgroups service. This was done so cgroups can be
+mounted inside an lxc/lxd container without using the other parts of the
+sysfs service.
+
+?As a result of this change, if you are upgrading, you need to add
+cgroups to your sysinit runlevel by running the following command as
+root:
+
+```
+# rc-update add cgroups sysinit
+```
+
+For more information, see the following issue:
+
+https://github.com/openrc/openrc/issues/187
+
+Consider this your second notification with regard to /etc/mtab being a
+file instead of a symbolic link.
+
+In this version, the mtab service will complain loudly if you have
+mtab_is_file set to yes and recommend that you change this to no and
+restart the mtab service to migrate /etc/mtab to a symbolic link.
+
+If there is a valid technical reason to keep /etc/mtab as a flat file
+instead of a symbolic link to /proc/self/mounts, we are interested and
+we will keep the support in that case. Please open an issue and let us
+know however. Otherwise, consider this your final notice that the mtab
+service will be removed in the future.
+
 ## OpenRC 0.33
 
 This version removes the "service" binary which was just a copy of

+
+# Syntax of Service Scripts
+
+Service scripts are shell scripts. OpenRC aims at using only the standardized 
+POSIX sh subset for portability reasons. The default interpreter (build-time 
+toggle) is `/bin/sh`, so using for example mksh is not a problem.
+
+OpenRC has been tested with busybox sh, ash, dash, bash, mksh, zsh and possibly 
+others. Using busybox sh has been difficult as it replaces commands with 
+builtins that don't offer the expected features.
+
+The interpreter for service scripts is `#!/sbin/openrc-run`.
+Not using this interpreter will break the use of dependencies and is not 
+supported. (iow: if you insist on using `#!/bin/sh` you're on your own)
+
+A `depend` function declares the dependencies of this service script.
+All scripts must have start/stop/status functions, but defaults are provided and should be used unless you have a very strong reason not to use them.
+
+Extra functions can be added easily:
+
+```
+extra_commands="checkconfig"
+checkconfig() {
+	doSomething
+}
+```
+
+This exports the checkconfig function so that `/etc/init.d/someservice 
+checkconfig` will be available, and it "just" runs this function.
+
+While commands defined in `extra_commands` are always available, commands
+defined in `extra_started_commands` will only work when the service is started
+and those defined in `extra_stopped_commands` will only work when the service is
+stopped. This can be used for implementing graceful reload and similar
+behaviour.
+
+Adding a restart function will not work, this is a design decision within 
+OpenRC. Since there may be dependencies involved (e.g. network -> apache) a 
+restart function is in general not going to work. 
+restart is internally mapped to `stop()` + `start()` (plus handling dependencies).
+If a service needs to behave differently when it is being restarted vs
+started or stopped, it should test the `$RC_CMD` variable, for example:
+
+```
+[ "$RC_CMD" = restart ] && do_something
+```
+
+# The Depend Function
+
+This function declares the dependencies for a service script. This
+determines the order the service scripts start.
+
+```
+depend() {
+	need net
+	use dns logger netmount
+	want coolservice
+}
+```
+
+`need` declares a hard dependency - net always needs to be started before this 
+	service does
+
+`use` is a soft dependency - if dns, logger or netmount is in this runlevel 
+	start it before, but we don't care if it's not in this runlevel.
+	`want` is between need and use - try to start coolservice if it is
+	installed on the system, regardless of whether it is in the
+	runlevel, but we don't care if it starts.
+
+`before` declares that we need to be started before another service
+
+`after` declares that we need to be started after another service, without 
+	creating a dependency (so on calling stop the two are independent)
+
+`provide` allows multiple implementations to provide one service type, e.g.:
+	`provide cron` is set in all cron-daemons, so any one of them started 
+	satisfies a cron dependency
+
+`keyword` allows platform-specific overrides, e.g. `keyword -lxc` makes this 
+	service script a noop in lxc containers. Useful for things like keymaps, 
+	module loading etc. that are either platform-specific or not available 
+	in containers/virtualization/...
+
+FIXME: Anything missing in this list?
+
+# The Default Functions
+
+All service scripts are assumed to have the following functions:
+
+```
+start()
+stop()
+status()
+```
+
+There are default implementations in `lib/rc/sh/openrc-run.sh` - this allows very 
+compact service scripts. These functions can be overridden per service script as 
+needed.
+
+The default functions assume the following variables to be set in the service 
+script:
+
+```
+command=
+command_args=
+pidfile=
+```
+
+Thus the 'smallest' service scripts can be half a dozen lines long
+
+## Don't write your own start/stop functions
+
+OpenRC is capable of stopping and starting most daemons based on the
+information that you give it. For a well-behaved daemon that
+backgrounds itself and writes its own PID file by default, the
+following OpenRC variables are likely all that you'll need:
+
+  * command
+  * command_args
+  * pidfile
+
+Given those three pieces of information, OpenRC will be able to start
+and stop the daemon on its own. The following is taken from an
+[OpenNTPD](http://www.openntpd.org/) service script:
+
+```sh
+command="/usr/sbin/ntpd"
+
+# The special RC_SVCNAME variable contains the name of this service.
+pidfile="/run/${RC_SVCNAME}.pid"
+command_args="-p ${pidfile}"
+```
+
+If the daemon runs in the foreground by default but has options to
+background itself and to create a pidfile, then you'll also need
+
+  * command_args_background
+
+That variable should contain the flags needed to background your
+daemon, and to make it write a PID file. Take for example the
+following snippet of an
+[NRPE](https://github.com/NagiosEnterprises/nrpe) service script:
+
+```sh
+command="/usr/bin/nrpe"
+command_args="--config=/etc/nagios/nrpe.cfg"
+command_args_background="--daemon"
+pidfile="/run/${RC_SVCNAME}.pid"
+```
+
+Since NRPE runs as *root* by default, it needs no special permissions
+to write to `/run/nrpe.pid`. OpenRC takes care of starting and
+stopping the daemon with the appropriate arguments, even passing the
+`--daemon` flag during startup to force NRPE into the background (NRPE
+knows how to write its own PID file).
+
+But what if the daemon isn't so well behaved? What if it doesn't know
+how to background itself or create a pidfile? If it can do neither,
+then use,
+
+  * command_background=true
+
+which will additionally pass `--make-pidfile` to start-stop-daemon,
+causing it to create the `$pidfile` for you (rather than the daemon
+itself being responsible for creating the PID file).
+
+If your daemon doesn't know how to change its own user or group, then
+you can tell start-stop-daemon to launch it as an unprivileged user
+with
+
+  * command_user="user:group"
+
+Finally, if your daemon always forks into the background but fails to
+create a PID file, then your only option is to use
+
+  * procname
+
+With `procname`, OpenRC will try to find the running daemon by
+matching the name of its process. That's not so reliable, but daemons
+shouldn't background themselves without creating a PID file in the
+first place. The next example is part of the [CA NetConsole
+Daemon](https://oss.oracle.com/projects/cancd/) service script:
+
+```sh
+command="/usr/sbin/cancd"
+command_args="-p ${CANCD_PORT}
+              -l ${CANCD_LOG_DIR}
+              -o ${CANCD_LOG_FORMAT}"
+command_user="cancd"
+
+# cancd daemonizes itself, but doesn't write a PID file and doesn't
+# have an option to run in the foreground. So, the best we can do
+# is try to match the process name when stopping it.
+procname="cancd"
+```
+
+To recap, in order of preference:
+
+  1. If the daemon backgrounds itself and creates its own PID file, use
+     `pidfile`.
+  2. If the daemon does not background itself (or has an option to run
+     in the foreground) and does not create a PID file, then use
+     `command_background=true` and `pidfile`.
+  3. If the daemon backgrounds itself and does not create a PID file,
+     use `procname` instead of `pidfile`. But, if your daemon has the
+     option to run in the foreground, then you should do that instead
+     (that would be the case in the previous item).
+  4. The last case, where the daemon does not background itself but
+     does create a PID file, doesn't make much sense. If there's a way
+     to disable the daemon's PID file (or, to write it straight into the
+     garbage), then do that, and use `command_background=true`.
+
+## Reloading your daemon's configuration
+
+Many daemons will reload their configuration files in response to a
+signal. Suppose your daemon will reload its configuration in response
+to a `SIGHUP`. It's possible to add a new "reload" command to your
+service script that performs this action. First, tell the service
+script about the new command.
+
+```sh
+extra_started_commands="reload"
+```
+
+We use `extra_started_commands` as opposed to `extra_commands` because
+the "reload" action is only valid while the daemon is running (that
+is, started). Now, start-stop-daemon can be used to send the signal to
+the appropriate process (assuming you've defined the `pidfile`
+variable elsewhere):
+
+```sh
+reload() {
+  ebegin "Reloading ${RC_SVCNAME}"
+  start-stop-daemon --signal HUP --pidfile "${pidfile}"
+  eend $?
+}
+```
+
+## Don't restart/reload with a broken config
+
+Often, users will start a daemon, make some configuration change, and
+then attempt to restart the daemon. If the recent configuration change
+contains a mistake, the result will be that the daemon is stopped but
+then cannot be started again (due to the configuration error). It's
+possible to prevent that situation with a function that checks for
+configuration errors, and a combination of the `start_pre` and
+`stop_pre` hooks.
+
+```sh
+checkconfig() {
+  # However you want to check this...
+}
+
+start_pre() {
+  # If this isn't a restart, make sure that the user's config isn't
+  # busted before we try to start the daemon (this will produce
+  # better error messages than if we just try to start it blindly).
+  #
+  # If, on the other hand, this *is* a restart, then the stop_pre
+  # action will have ensured that the config is usable and we don't
+  # need to do that again.
+  if [ "${RC_CMD}" != "restart" ] ; then
+    checkconfig || return $?
+  fi
+}
+
+stop_pre() {
+  # If this is a restart, check to make sure the user's config
+  # isn't busted before we stop the running daemon.
+  if [ "${RC_CMD}" = "restart" ] ; then
+      checkconfig || return $?
+  fi
+}
+```
+
+To prevent a *reload* with a broken config, keep it simple:
+
+```sh
+reload() {
+  checkconfig || return $?
+  ebegin "Reloading ${RC_SVCNAME}"
+  start-stop-daemon --signal HUP --pidfile "${pidfile}"
+  eend $?
+}
+```
+
+## PID files should be writable only by root
+
+PID files must be writable only by *root*, which means additionally
+that they must live in a *root*-owned directory. This directory is
+normally /run under Linux and /var/run under other operating systems.
+
+Some daemons run as an unprivileged user account, and create their PID
+files (as the unprivileged user) in a path like
+`/var/run/foo/foo.pid`. That can usually be exploited by the unprivileged
+user to kill *root* processes, since when a service is stopped, *root*
+usually sends a SIGTERM to the contents of the PID file (which are
+controlled by the unprivileged user). The main warning sign for that
+problem is using `checkpath` to set ownership on the directory
+containing the PID file. For example,
+
+```sh
+# BAD BAD BAD BAD BAD BAD BAD BAD
+start_pre() {
+  # Ensure that the pidfile directory is writable by the foo user/group.
+  checkpath --directory --mode 0700 --owner foo:foo "/var/run/foo"
+}
+# BAD BAD BAD BAD BAD BAD BAD BAD
+```
+
+If the *foo* user owns `/var/run/foo`, then he can put whatever he wants
+in the `/var/run/foo/foo.pid` file. Even if *root* owns the PID file, the
+*foo* user can delete it and replace it with his own. To avoid
+security concerns, the PID file must be created as *root* and live in
+a *root*-owned directory. If your daemon is responsible for forking
+and writing its own PID file but the PID file is still owned by the
+unprivileged runtime user, then you may have an upstream issue.
+
+Once the PID file is being created as *root* (before dropping
+privileges), it can be written directly to a *root*-owned
+directory.  For example, the *foo* daemon might write
+`/var/run/foo.pid`. No calls to checkpath are needed. Note: there is
+nothing technically wrong with using a directory structure like
+`/var/run/foo/foo.pid`, so long as *root* owns the PID file and the
+directory containing it.
+
+Ideally (see "Upstream your service scripts"), your service script
+will be integrated upstream and the build system will determine the
+appropriate directory for the pid file. For example,
+
+```sh
+pidfile="@piddir@/${RC_SVCNAME}.pid"
+```
+
+A decent example of this is the [Nagios core service
+script](https://github.com/NagiosEnterprises/nagioscore/blob/master/openrc-init.in),
+where the full path to the PID file is specified at build-time.
+
+## Don't let the user control the PID file location
+
+It's usually a mistake to let the end user control the PID file
+location through a conf.d variable, for a few reasons:
+
+  1. When the PID file path is controlled by the user, you need to
+     ensure that its parent directory exists and is writable. This
+     adds unnecessary code to the service script.
+
+  2. If the PID file path changes while the service is running, then
+     you'll find yourself unable to stop the service.
+
+  3. The directory that should contain the PID file is best determined
+     by the upstream build system (see "Upstream your service scripts").
+     On Linux, the preferred location these days is `/run`. Other systems
+     still use `/var/run`, though, and a `./configure` script is the
+     best place to decide which one you want.
+
+  4. Nobody cares where the PID file is located, anyway.
+
+Since OpenRC service names must be unique, a value of
+
+```sh
+pidfile="/var/run/${RC_SVCNAME}.pid"
+```
+
+guarantees that your PID file has a unique name.
+
+## Upstream your service scripts (for packagers)
+
+The ideal place for an OpenRC service script is **upstream**. Much like
+systemd services, a well-crafted OpenRC service script should be
+distribution-agnostic, and the best place for it is upstream. Why? For
+two reasons. First, having it upstream means that there's a single
+authoritative source for improvements. Second, a few paths in every
+service script are dependent upon flags passed to the build system. For
+example,
+
+```sh
+command=/usr/bin/foo
+```
+
+in an autotools-based build system should really be
+
+```sh
+command=@bindir@/foo
+```
+
+so that the user's value of `--bindir` is respected. If you keep the
+service script in your own distribution's repository, then you have to
+keep the command path and package synchronized yourself, and that's no
+fun.
+
+## Be wary of "need net" dependencies
+
+There are two things you need to know about "need net" dependencies:
+
+  1. They are not satisfied by the loopback interface, so "need net"
+     requires some *other* interface to be up.
+
+  2. Depending on the value of `rc_depend_strict` in `rc.conf`, the
+     "need net" will be satisfied when either *any* non-loopback
+     interface is up, or when *all* non-loopback interfaces are up.
+
+The first item means that "need net" is wrong for daemons that are
+happy with `0.0.0.0`, and the second point means that "need net" is
+wrong for daemons that need a particular (for example, the WAN)
+interface. We'll consider the two most common users of "need net";
+network clients who access some network resource, and network servers
+who provide them.
+
+### Network clients
+
+Network clients typically want the WAN interface to be up. That may
+tempt you to depend on the WAN interface; but first, you should ask
+yourself a question: does anything bad happen if the WAN interface is
+not available? In other words, if the administrator wants to disable
+the WAN, should the service be stopped? Usually the answer to that
+question is "no," and in that case, you should forego the "net"
+dependency entirely.
+
+Suppose, for example, that your service retrieves virus signature
+updates from the internet. In order to do its job correctly, it needs
+a (working) internet connection. However, the service itself does not
+require the WAN interface to be up: if it is, great; otherwise, the
+worst that will happen is that a "server unavailable" warning will be
+logged. The signature update service will not crash, and—perhaps more
+importantly—you don't want it to terminate if the administrator turns
+off the WAN interface for a second.
+
+### Network servers
+
+Network servers are generally easier to handle than their client
+counterparts. Most server daemons listen on `0.0.0.0` (all addresses)
+by default, and are therefore satisfied to have the loopback interface
+present and operational. OpenRC ships with the loopback service in the
+*boot* runlevel, and therefore most server daemons require no further
+network dependencies.
+
+The exceptions to this rule are those daemons who produce negative
+side-effects when the WAN is unavailable. For example, the Nagios
+server daemon will generate "the sky is falling" alerts for as long as
+your monitored hosts are unreachable. So in that case, you should
+require some other interface (often the WAN) to be up. A "need"
+dependency would be appropriate, because you want Nagios to be
+stopped before the network is taken down.
+
+If your daemon can optionally be configured to listen on a particular
+interface, then please see the "Depending on a particular interface"
+section.
+
+### Depending on a particular interface
+
+If you need to depend on one particular interface, usually it's not
+easy to determine programmatically what that interface is. For
+example, if your *sshd* daemon listens on `192.168.1.100` (rather than
+`0.0.0.0`), then you have two problems:
+
+  1. Parsing `sshd_config` to figure that out; and
+
+  2. Determining which network service name corresponds to the
+     interface for `192.168.1.100`.
+
+It's generally a bad idea to parse config files in your service
+scripts, but the second problem is the harder one. Instead, the most
+robust (i.e. the laziest) approach is to make the user specify the
+dependency when he makes a change to sshd_config. Include something
+like the following in the service configuration file,
+
+```sh
+# Specify the network service that corresponds to the "bind" setting
+# in your configuration file. For example, if you bind to 127.0.0.1,
+# this should be set to "loopback" which provides the loopback interface.
+rc_need="loopback"
+```
+
+This is a sensible default for daemons that are happy with `0.0.0.0`,
+but lets the user specify something else, like `rc_need="net.wan"` if
+he needs it. The burden is on the user to determine the appropriate
+service whenever he changes the daemon's configuration file.

-
-# Syntax of Service Scripts
-
-Service scripts are shell scripts. OpenRC aims at using only the standardized 
-POSIX sh subset for portability reasons. The default interpreter (build-time 
-toggle) is `/bin/sh`, so using for example mksh is not a problem.
-
-OpenRC has been tested with busybox sh, ash, dash, bash, mksh, zsh and possibly 
-others. Using busybox sh has been difficult as it replaces commands with 
-builtins that don't offer the expected features.
-
-The interpreter for initscripts is `#!/sbin/openrc-run`.
-Not using this interpreter will break the use of dependencies and is not 
-supported. (iow: if you insist on using `#!/bin/sh` you're on your own)
-
-A `depend` function declares the dependencies of this service script.
-All scripts must have start/stop/status functions, but defaults are provided.
-Extra functions can be added easily:
-
-```
-extra_commands="checkconfig"
-checkconfig() {
-	doSomething
-}
-```
-
-This exports the checkconfig function so that `/etc/init.d/someservice 
-checkconfig` will be available, and it "just" runs this function.
-
-While commands defined in `extra_commands` are always available, commands
-defined in `extra_started_commands` will only work when the service is started
-and those defined in `extra_stopped_commands` will only work when the service is
-stopped. This can be used for implementing graceful reload and similar
-behaviour.
-
-Adding a restart function will not work, this is a design decision within 
-OpenRC. Since there may be dependencies involved (e.g. network -> apache) a 
-restart function is in general not going to work. 
-restart is internally mapped to `stop()` + `start()` (plus handling dependencies).
-If a service needs to behave differently when it is being restarted vs
-started or stopped, it should test the `$RC_CMD` variable, for example:
-
-```
-[ "$RC_CMD" = restart ] && do_something
-```
-
-# The Depend Function
-
-This function declares the dependencies for a service script. This
-determines the order the service scripts start.
-
-```
-depend() {
-	need net
-	use dns logger netmount
-	want coolservice
-}
-```
-
-`need` declares a hard dependency - net always needs to be started before this 
-	service does
-
-`use` is a soft dependency - if dns, logger or netmount is in this runlevel 
-	start it before, but we don't care if it's not in this runlevel.
-	`want` is between need and use - try to start coolservice if it is
-	installed on the system, regardless of whether it is in the
-	runlevel, but we don't care if it starts.
-
-`before` declares that we need to be started before another service
-
-`after` declares that we need to be started after another service, without 
-	creating a dependency (so on calling stop the two are independent)
-
-`provide` allows multiple implementations to provide one service type, e.g.:
-	`provide cron` is set in all cron-daemons, so any one of them started 
-	satisfies a cron dependency
-
-`keyword` allows platform-specific overrides, e.g. `keyword -lxc` makes this 
-	service script a noop in lxc containers. Useful for things like keymaps, 
-	module loading etc. that are either platform-specific or not available 
-	in containers/virtualization/...
-
-FIXME: Anything missing in this list?
-
-# The Default Functions
-
-All service scripts are assumed to have the following functions:
-
-```
-start()
-stop()
-status()
-```
-
-There are default implementations in `lib/rc/sh/openrc-run.sh` - this allows very 
-compact service scripts. These functions can be overridden per service script as 
-needed.
-
-The default functions assume the following variables to be set in the service 
-script:
-
-```
-command=
-command_args=
-pidfile=
-```
-
-Thus the 'smallest' service scripts can be half a dozen lines long
