It defines a variable and its default value in load_rc_config() just after
rc.conf is loaded. "rcvar" command shows the current and the default values.
This is an attempt to solve a problem that rc.d scripts from third-party
software do not have entries in /etc/defaults/rc.conf. The fact that
load_rc_config() reads rc.conf only once and /etc/rc invokes the function
before running rc.d scripts made developers confused for a long time because
load_rc_config() just before run_rc_command() in each rc.d script overrides
variables only when the script is directly invoked, not from /etc/rc.
Variables defined in set_rcvar are always set in load_rc_config() after
loading rc.conf. An rc.d script can now be written in a self-contained
manner regarding the related variables as follows:
---
name=foo
rcvar=foo_enable
set_rcvar foo_enable YES "Enable $name"
set_rcvar foo_flags "-s" "Flags to $name"
...
load_rc_config $name
run_rc_command "$@"
---
The following warnings were displayed:
sysctl: net.inet.ip.sourceroute=0: Operation not permitted
sysctl: net.inet.ip.accept_sourceroute=0: Operation not permitted
particularly useful for services such as "network" (netif) where each
interface can now have its own separate configuration file.
Add /etc/rc.conf.d to the mtree file so it is always present.

the first alias had to be _alias0 and processing stopped at the first non-
defined variable (preventing gaps). Allowing gaps gives the administrator
the ability to group aliases in an adhoc manner and also lifts the
requirement to renumber aliases simply to comment-out an existing one.
Aliases are processed in numerical ascending order.

command line options. The "jail_<jname>_*" rc.conf(5) variables for
per-jail configuration are automatically converted to
/var/run/jail.<jname>.conf before the jail(8) utility is invoked.
This is transparently backward compatible.

generates a configuration suitable for running unbound as a caching
forwarding resolver, and configures resolvconf(8) to update unbound's
list of forwarders in addition to /etc/resolv.conf. The initial list
is taken from the existing resolv.conf, which is rewritten to point to
localhost. Alternatively, a list of forwarders can be provided on the
command line.
To assist this script, add an rc.subr command called "enabled" which
does nothing except return 0 if the service is enabled and 1 if it is
not, without going through the usual checks. We should consider doing
the same for "status", which is currently pointless.
Add an rc script for unbound, called local_unbound. If there is no
configuration file, the rc script runs local-unbound-setup to generate
one.
Note that these scripts place the unbound configuration files in
/var/unbound rather than /etc/unbound. This is necessary so that
unbound can reload its configuration while chrooted. We should
probably provide symlinks in /etc.

The rules themselves typically have shell-like patterns and it is

1. Add new functionality to the force_depend method to incorporate the
tests for whether the service is enabled and/or already running.
2. Add a new option to bypass checking only that the service is enabled
at boot time, and always check if it is running.
3. Use this new functionality to greatly simplify the rc.d scripts that
use force_depend.
4. Add a force_depend for statd in lockd
5. Remove the check that either nfs_server or nfs_client is _enable'd
from statd and lockd. This was always overkill, and prevented using
the {one|force}start options, as well as stop'ing on the command line.
6. The yp* scripts had some of their arguments in various weird orders.
Bring them into line with the model.
7. If mountd fails to create /var/db/mountdtab, err out.
Ideas, suggestions, and/or review from delphij and jilles.
Pointy hats are completely my responsibility however.
The concept of set_rcvar() was nice in theory, but the forks
it creates are a drag on the startup process, which is especially
noticeable on slower systems, such as embedded ones.
Document the current semantics of the 'quiet' command prefix
in the rc.subr(8).
Fix dhclient rc.d script: it should not call err() for
non-DHCP-enabled interface when it is called from devd, because the
latter just blindly calls 'service dhclient quietstart' on each "link
up" event.
Since the 'quietstart' will silence the message "Cannot 'start' <foo>.
Set <foo>_enable to YES in /etc/rc.conf or use 'onestart' instead of
'start'." and running dhclient on the non-DHCP-enabled interface is
the same thing as running the service <foo> without <foo>_enable set,
such modification is in sync with the current semantics of the 'quiet'
prefix.

With the current sh, placing eval in a command substitution always results
in a fork(), even if it is the only command and only executes a single
simple command. Therefore, avoid it where it can be avoided easily.
Side effect: values starting with a hyphen and all whitespace are preserved.
The values are defaults and names for rc.conf variables and messages to be

that is running even though not _enable'd had an annoying side effect.
If the service was already started at boot time by another means when
the related script came around again in rcorder it would start again,
regardless of _enable, because there was a valid pid. [1]
So, split the test into 2 parts, one for (!rcvar && !stop), and one
for (stop && !valid_pid). This preserves the behavior from r206686
while preventing the undesired side effect.

to repeatedly read the conf files. Depending on what is enabled the
files are being read anywhere from 15, 30, or more times currently.
By loading the values in the environment this is reduced to 1, with
perhaps a couple more, again depending on what is enabled.
The speed-up for boot and shutdown is negligible when rc.conf is
on local disk, noticable when accessing files over NFS, and dramatic
when pulling rc.conf values from a database.
This change also includes a minor optimization to the conditional
for $_rc_conf_loaded.
still exists as a zombie. The 'kill -0' test in this function can
therefore return true even if the process isn't actually running.
This could lead to wait_for_pids() printing an endless string of the
pid number until the zombie finally exits.
Solve this problem by moving the sleep up to after the 'kill -0' test, but
only after we've run through the function once already. In the common case
(only one pid in the list) this will always do the right thing. On the rare
occasion that there is more than one pid in the list this will sleep 1
second per zombie process which will allow that process, and any other
in the list a chance to exit.
While I'm here, local'ize the variables that this function uses.
This waits for the requested process(es) to terminate, rather than polling
with an interval of 2 seconds.
If pwait is not available, the old method is used.
