Using udev-054, and kernel 2.6.11-ck1, /dev/sg0 and /dev/sg1 have permissions root:root - all other /dev/sg* devices have permissions root:cdrw. I have a real scsi cd burner on an Adaptec scsi card, cdrecord cannot write to /dev/sg0 as a normal user (who is in the cdrw group), due to permissions. If I manually 'chgrp cdrw /dev/sg0', cdrecord (and k3b) can write cd's OK. This manual change does not survive a reboot. Device tarball saving at shutdown is enabled. I assume this does not save the device permissions. I could not see any mention of /dev/sg* devices in the rules/permissions files in /etc/udev.

I think this has already been closed out, as it isn't a bug. I can't mark all sg devices as cdroms, as they are not. If you want this, please just add a custom udev rule to do so.
