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

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