optical devices now in disk group instead of cdrom

All,

someone on gentoo just reported to me that the following rule has been deleted from udev-174, which is leaving his optical devices in the standard "disk" group. He does not want to add his users to this group.

SUBSYSTEM=="block", KERNEL=="sr[0-9]*", SYMLINK+="scd%n", GROUP="cdrom"

Did you intend to move optical devices to the disk group?

Thanks,

William

I'm having similar questions from Arch users, so would also be interested in an explanation. Especially, why /dev/srX is not assigned the same group as the corresponding /dev/sgX.

On a (possibly) related note: The 'sg' module is no longer loaded explicitly (as of 'rules: do not load sg module'). Why is this no longer needed, and how is it supposed to work? I have heard of problems with missing /dev/sgX devices, but have not yet figured out exactly what the problem was (too many weird things going on).

Cheers,

Tom

No, that wasn't intentional, only the symlinks were meant to be removed. Added the permissions setting back now.

Thanks,
Kay

The sg devices are replaced by the bsg devices or by the SG_IO commands on the block device. The few people who rely on the legacy ones should just force-load the module, udev does no longer unconditionally load it.
