Revision 1.7, Tue Sep 19 13:04:38 2000 UTC (18 years, 5 months ago) by lukem
Branch: MAIN
Changes since 1.6: +3 -5 lines

- 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
