I'm trying to write a sensible rc.d script for cups-browsed.
Unfortunately,
cups-browsed itself does not daemonize. Now, that's not hard in shell:
( cd /; cups-browsed "$@" <&- >&- 2>&- & echo "$!" >$pidfile ) &
but how do I incorporate that into an rc.d script? There seems to be
no way
to set command to a shell function executing that code. If I set my
own
start_cmd, I loose all the magic foo rc.subr does for me. do I need to
put
that piece of code into a shell wrapper file or is there a simpler and
more elegant way?
Look at overriding start_precmd instead. Example:
https://github.com/NetBSD/pkgsrc/blob/trunk/mail/qmail-run/files/qmailqread.sh
I'm not sure how I first figured this out, and I don't do all the
daemonizing steps you've suggested, but this technique has been working
pretty well for me for quite some time.
