I think the count is higher than one or two. cdrecord - now cdrtools - has broken in the past. However, I'd be surprised if more than one or two broke across any upgrade that stretch across more than one release other than a .0 one. As it is, I've run packages built for 3.x on a 5-current system, with little problem. I don't recommend it as a practice, though. http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
