e43ee29eb4 supervise-daemon: do not use the exec_service() function
In order to run healthcheck() and the unhealthy() function, add an
exec_command call to the supervisor.
Another difference is This function also logs errors instead of
attempting to display them.

This is for #271.

a3555b1442 Add debug logging to start-stop-daemon and rc-supervisor
This will make it easier to track down why the supervisor intermittently
hangs after it runs for a long time.

b8e57c693a init.d/agetty: set default respawn period to 60 seconds
Without a respawn period setting, the supervisor will give up on
respawning agetty after it is respawned respawn_max times. For most
daemons giving up like this is reasonable, but not for agettys. Agettys
should always be respawned unless they are respawning too fafst,.

If an agetty is respawning faster than 10 times in 60 seconds, this
seems to be too fast.

af70862a7a supervise-daemon: use a default pid file if one is not specified

use of a pid file if this is possible.

ff4af908a5 Revert "checkpath: use O_PATH when available"
This reverts commit 2af0cedd59.

After speaking with Luis Ressel on the Gentoo selinux team, I am reverting
this commit for the following reasons:

- Luis told me that he feels this is not the solution we need to address
  the concern with checkpath; I will be working with him on another
  solution.

- There are concerns about the way the path variable was handled
  and the assert() call.
  The path variable should be dynamically allocated using xasprintf
  instead of defining a length at compile time. This would eliminate the
  need for the assert() call.

- It introduces the definition of _GNU_SOURCE which makes it
  easier to introduce portability concerns in the future (see #262).

2af0cedd59 checkpath: use O_PATH when available
This avoids opening directories/files with read permission, which is
sometimes rejected by selinux policy.

2504a2c25b Do not complain if interrupted by a signal
In start-stop-daemon and rc-schedules, we were printing out a warning if
the nanosleep call was interrupted by a signal, but we did not treat
this as an error situation other than displaying the message, so there
is no need for the message.

These are needed to allow keymaps and termencoding to run earlier in the

710c874e6e supervise-daemon: fix respawn_max off by one
Fix the comparison between respawn_count and respawn_max so that
respawn_max = 1 will allow for one respawn. Since respawn_count is
incremented before the comparison, use a 'greater than' comparison
so that respawn will be triggered when respawn_count is equal to
respawn_max.

0200002b8c start-stop-daemon: don't fail stopping if pidfile is gone
If pidfile does not exist when we are stopping the daemon, assume it is
already stopped, and report success.

hostapd is an example of a daemon which removes its pidfile when it is
exiting. If this daemon terminates prematurely, that is, without s-s-d
involvement, then openrc fails to restart it, because s-s-d "stop"
command fails when pidfile is missing.

16ff3cd8df check whether /sys/fs/cgroup is a mountpoint
The current check only tries to detect whether /sys/fs/cgroup exists and
whether it is writable or not. But when the init system doesn't mount
cgroups then /sys/fs/cgroup will just be an empty directory. When paired
with unprivileged containers that mount sysfs this will cause misleading
errors to be printed since /sys/fs/cgroup will be owned by user
nobody:nogroup in this case. Independent of this specific problem this
check will also be misleading when the /sys/fs/cgroup exists and is in
fact writable by the init system but isn't actually a mountpoint.

Note from William. "grep -qs" doesn't need to redirect output to
/dev/null since it is completely silent.

This fixes #209.

We need a version of this code because it is not available on glibc at
least without defining _GNU_SOURCE, and I would rather not do that.

c1ffe4d9f2 man/openrc-run.8: fix mountinfo args.
The "Ar" tag for the mountinfo command contained a typo (leading

  mountinfo ... <mount1> <mount2>

a7c99506d9 Fix repeated dependency cache rebuild if clock skewed
rc_deptree_update_needed would return early as soon as it found
any file newer than the existing dependency cache.  Unfortunately,
the first file found may not be the newest one there; so the
clock skew workaround in rc-misc:_rc_deptree_load would be given
a timestamp that was still too old.

This fix forces a full scan of all relevant files, so as to
ensure that we return a timestamp that will allow the clock skew
fix to operate.   The runtime cost is no worse than the case where
the cache is up to date (ie. we must check every possible file).

This fixes #161.

run the appropriate service manager commands.

0ddee9b7d2 openrc-init: fix buffer overflow in init.ctl
How to reproduce 1-byte overflow:

```
$ FEATURES=-test CFLAGS="-fsanitize=address -O0 -ggdb3" emerge -1 openrc

=================================================================
==1==ERROR: AddressSanitizer: stack-buffer-overflow on address 0x7fff0efd8710

    #0 0x401cfb  (/sbin/openrc-init+0x401cfb)

  This frame has 3 object(s):
    [32, 160) 'signals'
    [192, 344) 'sa'
    [384, 2432) 'buf' <== Memory access at offset 2432 overflows this variable
HINT: this may be a false positive if your program uses some custom stack unwind mechanism or swapcontext
      (longjmp and C++ exceptions *are* supported)
SUMMARY: AddressSanitizer: stack-buffer-overflow ??:0 ??
```

The problem here is in the code handling reads from 'init.ctl':

```
int main(int argc, char **argv) {
...
    char buf[2048];
    for (;;) {
        /* This will block until a command is sent down the pipe... */
        fifo = fopen(RC_INIT_FIFO, "r");
        count = fread(buf, 1, 2048, fifo);
        buf[count] = 0;
        ...
    }
```

`buf[count] = 0;` writes outside the buffer when `fread()` returns non-truncated read.

This fixes #138.

# 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 0.40
In this version, the keymaps and termencoding services on Linux needed
to be modified so they do not write to the root file system. This was
done so they can run earlier in the boot sequence. AS a result, you will
need to add save-termencoding and save-keymaps to your boot runlevel.
This can be done as follows:
```
# rc-update add save-keymaps boot
# rc-update add save-termencoding boot
```
## OpenRC 0.39
This version removes the support for addons.
The only place I know that this was used was Gentoo Baselayout 1.x, so
it shouldn't affect anyone since baselayout-1 has been dead for a few
years.
Since all supported Linux kernel versions now make efivarfs immutable
and all of the tools that access efivarfs are aware of this, we no
longer mount efivarfs read-only. See the following github issue for more
information:
https://github.com/openrc/openrc/issues/238
This version adds timed shutdown and cancelation of shutdown to
openrc-shutdown. Shutdowns can now be delayed for a certain amount of
time or scheduled for an exact time.
supervise-daemon supports health checks, which are a periodic way to make sure a
service is healthy. For more information on setting this up, please see
supervise-daemon-guide.md.
The --first-time switch has been added to all modprobe commands in the
modules service. This means that, on Linux, you will see failures if a
module was loaded by an initramfs or device manager before this service
runs. These messages are harmless, but to clean them up, you should adjust your
modules autoload configuration.
## OpenRC 0.37
start-stop-daemon now supports logging stdout and stderr of daemons to
processes instead of files. These processes are defined by the
output_logger and error_logger variables in standard service scripts, or
by the -3/--output-logger or -4/--error-logger switches if you use
start-stop-daemon directly. For more information on this, see the
start-stop-daemon man page.
## OpenRC 0.36
In this release, the modules-load service has been combined into the
modules service since there is no reason I know of to keep them
separate. However, modules also provides modules-load in case you were
using modules-load in your dependencies.
The consolefont, keymaps, numlock and procfs service scripts no longer
have a dependency on localmount.
If you are a linux user and are still separaating / from /usr,
you will need to add the following line to the appropriate conf.d files:
rc_need="localmount"
## 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
"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:

.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.

Invoking supervise-daemon requires both the RC_SVCNAME environment
variable to be set and the name of the service as the first argument on
the command line, so it is best to invoke it inside a service script

OpenRC Service Script Writing Guide
===================================
This document is aimed at developers or packagers who
write OpenRC service scripts, either for their own projects, or for
the packages they maintain. It contains advice, suggestions, tips,
tricks, hints, and counsel; cautions, warnings, heads-ups,
admonitions, proscriptions, enjoinders, and reprimands.
It is intended to prevent common mistakes that are found "in the wild"
by pointing out those mistakes and suggesting alternatives. Each
good/bad thing that you should/not do has a section devoted to it. We
don't consider anything exotic, and assume that you will use
start-stop-daemon to manage a fairly typical long-running UNIX
process.
# 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.
