This occurs before the first load_rc_config() so that it may be
overridden by the user, and appears in single quotes so the
variables don't get evaluated until the eval in run_rc_command().
Problem noted by Patrick Welche <prlw1@cam.ac.uk> in [bin/15912].
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
fine as was, the result was the line `start_precmd=start_precmd' which
looked odd. Pointed out by Bernd Ernesti.
While here, add NetBSD RCS Id.
BTW, to clarify, as people have asked: this script does not support
pkgsrc/security/sshd -- that package comes with a perfectly fine rc script
which in addition to supporting /etc/rc.d can also be used with 1.4.X.
This script will not trivially work with the ssh package as it a.) calls
the ssh commands at the pathnames they will be installed at by usr.bin/ssh,
and b.) generates a DSA key as well as an RSA key.
on ${SSHDIST}, as with usr.bin/ssh itself.
This script includes a `keygen' target for regenerating RSA and DSA host keys,
and invokes this if these keys are not present when sshd is started up.
