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. 2002-03-22 04:33:57 +00:00			`# $NetBSD: ipnat,v 1.7 2002/03/22 04:33:58 thorpej Exp $`

- 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 $rcvar isn't set. these above changes fix PR [bin/11027]. - when doing `force', ignore the return value of _precmd. this fixes PR [bin/10781]. - rename what sysdb provides from `databases' to `sysdb', to reflect the name of the script. - improve the comments in rc.subr 2000-09-19 13:04:38 +00:00			`rcvar=$name`

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. 2000-05-13 08:45:06 +00:00			`load_rc_config $name`
