Rename NETWORK to NETWORKING, to allow rc.d to be on a case insensitive file system (prevents conflict with 'network'). PROVIDE both NETWORKING and NETWORK (the latter for compatibility with 3rd party scripts). 2002-01-31 04:26:05 +03:00			`# REQUIRE: NETWORKING syslogd`

- 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 $rcvar isn't set. these above changes fix PR [bin/11027]. - when doing `force', ignore the return value of _precmd. this fixes PR [bin/10781]. - rename what sysdb provides from `databases' to `sysdb', to reflect the name of the script. - improve the comments in rc.subr 2000-09-19 17:04:38 +04:00			`rcvar=$name`

- Rename a bunch of "internal" run_rc_command() variables and officially make them "externally" available: Previous Current Purpose -------- ------- ------- _arg rc_arg Argument to command, after fast/force processing performed (and prefix removed) _flags rc_flags Flags to start the default command with. Defaults to ${name}_flags, unless overridden by $flags from the environment. This variable may be changed by the precmd method. _pid rc_pid PID of command (if appropriate). _rc_run_fast rc_fast Not empty is "fast" was provided. _rc_run_force rc_force Not empty is "force" was provided. - Use rc_flags instead of _flags or ${name}_flags in various rc.d scripts, so that $flags from the environment overrides ${name}_flags from rc.conf(5). Fixes [bin/15800]. 2002-03-22 07:16:38 +03:00			`ntpdate $rc_flags $ntpdate_hosts`

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 12:45:06 +04:00			`load_rc_config $name`
