define procname or have a PID file. This might be useful for cases,
such as mounting local FS, when there is no running daemon
still some other persistent state in the system which status
can be checked.
It is still possible to have a status method before this by having
extra_commands="status", but it's not obvious and might give
an script writer some extra legwork to figure out how and why
the straight method is not working.

This is a more reliable method that accounts for existing pidfiles,
procname and interpreter settings.
Current method of obtaining the pid for oomprotect="YES"|"ALL" processes
in certain cases fails to find a unique pid.
One such case are rc.d scripts defining command as:
command="daemon"
which results in all processes started via daemon being selected and
passed to protect(1) which fails and prints usage:
$ /etc/rc.d/exampled restart
Stopping exampled.
Starting exampled.
usage: protect [-i] command
protect [-cdi] -g pgrp | -p pid
Running the same with -x reveals what happens:
+ pid='3051 4268 4390 4421 4427 4470 4588 4733 4740 4870 4949 4954 4979

+ /usr/bin/protect -p 3051 4268 4390 4421 4427 4470 4588 4733 4740 4870
4949 4954 4979 5835 5866 55487 55583 56525 57643 57789 57882 58072 58167
99419
usage: protect [-i] command
protect [-cdi] -g pgrp | -p pid
We have a more reliable way of obtaining pid already defined in rc.subr
and available when protect(1) needs it. We can simply `eval $_pidcmd`
which also invokes `check_process` but properly accounts for existing
pidfile, procname and interpreter settings.
With the change the pidfile is properly obtained.

A user may set ${name}_env variable in rc.conf(5) in order to set additional
environment variables for a service command. Unfortunately, at the moment
this variable is only honored when the command is specified via the command
variable. Those additional environment variables coming from ${name}_env
are never set if the service is started via the ${rc_arg}_cmd variable (for
example start_cmd).

Since r233109, kldload has the -n option, which silently ignores options
that are already loaded.

Note that this script no longer reports if the module is already loaded,
but it could be argued this wasn't particularly useful information.

Originally intended as 'in case in needs to be re-invoked', but it was later
decided (by myself) that 're-invoke itself' makes it more clear that the
script is expected to use this in a way.

Some rc scripts in ports (e.g. uwsgi, apache, openvpn) allow for
'application profiles' that usually require the rc script to be invoked
again for each active profile. Because there's no consistent way to
determine the path because it differs between manual/service(8) invocations
and /etc/rc invocations, this leads to patterns like these:
- www/uwsgi hardcodes the script path
- security/openvpn guesses either $_file or $0 based on $0 = /etc/rc
Instead of forcing rc scripts to guess, provide an rc_service variable to
the scripts that gets set appropriately both for direct execution or when a
script is being executed via run_rc_script (e.g. /etc/rc).
This is our analog of an OpenRC variable with the same name, different case
(RC_SERVICE).

'read' pessimistically read(2)s one byte at a time, which can be quite
silly for large environments in slow emulators.
In my boring user environment, truss shows that the number of read()
syscalls to source rc.subr and invoke list_vars is reduced by something like
3400 to 60. ministat(1) shows a significant time difference of about -71%
for my environment.

This adds new keywords to rc/service to enable/disable a service's
rc.conf(5) variable and "delete" to remove the variable.
When the "service_delete_empty" variable in rc.conf(5) is set to "YES"
(default is "NO") an rc.conf.d file (in /etc/ or /usr/local/etc) is
deleted if empty after modification using "service $foo delete".

The reasons for this are forward looking to pkgbase:
* /sbin/init is a special binary; try not to replace it with
every package update because an rc script was touched.
(a follow-up commit will make init its own package)
* having rc in its own place will allow more easy replacement
of the rc framework with alternatives, such as openrc.
