No, you don't need to install anything - it's part of rc.subr.
=46rom 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=3DYES.
force Skip the checks for rcvar being set to ``YES'', and
sets rc_force=3DYES. 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=
=20
service before enabling it in rc.conf.
I also use it with NFS. Whenever I've changed /etc/exports, I force mountd =
to=20
reread it by issuing
/etc/rc.d/mountd onereload
