Re: rc.d: how to daemonize a non-daemonizing daemon?

I'm trying to write a sensible rc.d script for cups-browsed. Unfortunately,

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:

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.
