Description Philippe Troin 2005-12-07 12:12:32 UTC 
With the default udev configuration, the /dev/sg* devices (SCSI generic) are
owned by root:root with permissions 660.

For /dev/sg* devices corresponding to cdrom drives, /dev/sg* should be owned by
root:cdrom (still with permissions 0660).

Having CD-ROM sg devices inacessibles by members of the cdrom group breaks a lot
of assumptions in gentoo (cdrecord fails, the gnome desktop (see bug #114788 for
example)).

Adding this line to /etc/udev/rules.d/some_rule_file does the trick:

BUS=="scsi",    KERNEL="sg[0-9]+", ACTION=="add", DRIVER=="sr", GROUP="cdrom"


Reproducible: Always
