Undo change to a comment made when I thought another change to the
script was needed ... the unnecessary script change was never committed,
but the comment that described it was... No functional change.

The config file is not required to exist (unless specified via -d).
(reported by rhialto@falu.nl) Don't fail to start if it doesn't.

Make sure the directory for the config file exists inside the chroot before
attempting to copy into it ("confdir" was calculated, but never used...)

While here, fix getopts usage (obviously only ever previously tested when
the -c arg was the first option...) and don't use test(1)'s -o operator
(especially not when one of the other args is an unknown string).
If -c is given (and we will chroot), require filename to be full path.

Misc minor style cleanups.

Add _rtadvd user and group.
Add a chroot dir for the _rtadvd user.
Drop privs to the user _rtadvd after acquiring our socket.
When rc.d/rtadvd starts or reloads, the rtadvd config file is copied
into the chroot before starting or reloading rtadvd itself.
Create a symlink from /var/run/rtadvd.dump to the chroot

Inital idea from OpenBSD patch rtadvd.c r1.36

Add a pidfile and the reload command.

branches: 1.6.50; 1.6.56;
Add an _rc_subr_loaded variable, set to ":" by rc.subr. Scripts can use this
for a speedup by doing:
$_rc_subr_loaded . /etc/rc.subr

Correct the "direction" of the barrier dependencies (DAEMON, LOGIN,
NETWORKING, and SERVERS) by specifying that certain things should
come BEFORE a given barrier, rather than having the barrier REQUIRE
a service. This allows scripts to be removed without having to
edit the barrier dependencies.

As discussed on tech-userlevel, and approved by Luke.

- only perform the checkyesno on the variable named in $rcvar (rather than
implicitly using $name if $rcvar isn't set), and always perform this check,
even when using start_cmd (et al).
this check is performed before the pidcmd
is run, speeding up scripts that weren't going to be run anyway.
this should speed up booting slow systems.

- take advantage of the above and remove
start_precmd="checkyesno foo"
in scripts that use start_cmd.

- explicitly set rcvar=foo in the rc.d/foo scripts which have an equivalent
rc.conf entry

- fix `rcvar' and `restart' when $rcvar isn't set.
these above changes fix PR [bin/11027].

- when doing `force*', ignore the return value of *_precmd.
this fixes PR [bin/10781].

- rename what sysdb provides from `databases' to `sysdb', to reflect
the name of the script.

- improve the comments in rc.subr

branches: 1.3.4;
Use load_rc_config() (from rc.subr) instead of sourcing /etc/rc.conf.
This allows us or a user to change the configuration file method in
one place - rc.subr - without having to edit all of the rc.d/* files.

* replace daemon, login, servers with DAEMON, LOGIN, SERVERS
* remove sshd (it was from my private system)
