People keep talking about forcestart.
Unless I'm misunderstanding things horribly, forcestart does exactly that
- forces the service to start regardless of any error that may occur.
The better option for starting something as a one-off (not enabled in
rc.conf) is mnemonically named onestart - which only ignores the rcvar
but still fails on any other error.
And yes, I like having onestart/onestop distinguished from start/stop.
I believe it "forces" a start even though its not actually enabled (in
rc.conf) rather than regardless of errors.
If you really want a command line of onestart/onestop install the
sysutils/bsdadminscripts port which has a script called rconestart and
rconestop which do exactly that ;)
No, you don't need to install anything - it's part of rc.subr.
From the rc.subr(8) manpage:
argument may have one of the following prefixes which alters its
operation:
fast Skip the check for an existing running process, and
sets rc_fast=YES.
force Skip the checks for rcvar being set to ``YES'', and
sets rc_force=YES. This ignores argument_precmd
returning non-zero, and ignores any of the required_*
tests failing, and always returns a zero exit status.
one Skip the checks for rcvar being set to ``YES'', but
performs all the other prerequisite tests.
I certainly use onestart - generally when I'm configuring and testing a new
service before enabling it in rc.conf.
I also use it with NFS. Whenever I've changed /etc/exports, I force mountd to
reread it by issuing
/etc/rc.d/mountd onereload
Doh I just skimmed though /etc/rc.subr not the manpage, thanks for the
pointers.
