What configuration files/scripts control permissions for cd/dvd drive

[parish]

As a followup to my thread [SOLVED] k3b: "No optical drive found", I'm trying to locate the configuration files/scripts that control the default permissions for the cd/dvd device (/dev/sr0) and the permissions assigned when a disk is inserted.

The issue is that when I change the device permissions to permit ugo+rw access, it is reset to its default ug+rw state upon insertion of a disk.

Thanks for your help.

Start by examining /usr/lib/udev/rules.d/50-udev-default.rules
It may be as easy as adding a MODE= to the line
SUBSYSTEM=="block", KERNEL=="sr[0-9]*", GROUP="cdrom"/home/stevea/.kde/share/config/kded_device_automounterrc
Or perhaps OWNER=..., GROUP=...
That may vary from release to release but addresses the device permissions issue.

WRT to the automount permissions, thats a desktop matter.

Try to install cdrecord from here http://cdrecord.berlios.de/private/cdrecord.html

It is usually installed suid root, so it has full access to the DVD drive.
