1 Hi folks!

3 For years I've been using cdrecord as a non-root user and without suid
4 bit set. Now it doesn't work any more. Here is the error message and
5 some other info:

73 I can't find anything, neither in the ChangeLogs (ebuild or cdrtools)
74 nor on the forums/bugzilla. Everybody seems to like the idea of burning
75 CDs with root permissions. Can anybody point me in the right direction?

78 Thanks,
