Question about perms for native ATAPI burning
Okay, I'm confused. When I try to burn cd's as a regular user, cdrecord tells me:

cdrecord: Drive does not support SAO recording.
cdrecord: Illegal write mode for this drive.

The odd thing is that the supported mode line is blank, like this:

Supported modes:

- If I do it as root, it works fine, and the mode line is:
Supported modes: TAO PACKET SAO SAO/R96P SAO/R96R RAW/R96R

- If I sudo it, it works fine

- Permissions are:
brw-rw---- 1 matt cdrw 22, 0 May 8 21:33 /dev/hdc
crw-rw---- 1 matt cdrw 21, 0 May 8 21:35 /dev/sg0
-rws--x--- 1 root cdrw 346724 Jul 3 22:26 /usr/bin/cdrecord

(I don't even know if the sg0 is necessary, I just applied the permissions that I used to use for IDE-SCSI to this)

I would prefer not to have to su or sudo this, since it plays hell with NFS mounted homedirs (root squash and all that).

Any ideas?
