Yup. That's what I thought. So, the instructions on the gcombust page
(http://www.abo.fi/~jmunsin/gcombust/FAQ.shtml) about getting it to work
as a regular user ("gcombust shouldn't be ran as root") are ...
irrelevant? contradictory? misleading? The only alternative is to make
cdrecord setgid and give the group executable rights, I guess.
