release) to not start postfix if $postfix is not explicitely set and
another mailer is selected in /etc/mailer.conf. Also print a warning if it
happens because the mailer in rc.conf is the removed sendmail.
This prevents starting two MTAs at once if one uses a custom MTA.
As proposed on tech-userlevel, approved by martin.
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
