I don't want to say too much, it being OT and all, but a change in Linux 2.6.8 has meant that I have to run my burning software as root to get a reliable burn. I've yet to find a solution to that problem. > PS another way to do this would be to create a devd file which does the > chmod's for this particular device (instead of blindly changing all da > devices). I have things working, I'm happy. :-) I'll look at other options and better set ups when I have either the need or the time. :-) -- Andy. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"

It turns out I had completely missed the rc.conf line above so obviously restarting devfs had no effect. Many thanks Daniel. It's working just how I want it now. :-) [1] One of the reasons I first tried FreeBSD as a desktop OS was because it has better support for CD/DVD burning as a user than Linux does (I still can't get burning working reliably with Gentoo but FreeBSD works flawlessly).
