the right way to access CDROM as non-root
I have a hard disk on /dev/hda and a CDROM drive on /dev/hdc.
Their permissions are:
brw-rw---- 1 root disk 3, 0 Jul 6 2000 /dev/hda
brw-rw---- 1 root disk 22, 0 Jul 6 2000 /dev/hdc
I want to access the CDROM drive as a non-root user
(to play my music CD). Adding my ordinary account to
the group "disk" is dangerous (anyone in the group "disk"
can reformat my hard disk), so I am looking for another solution.
The right way seems to be "chgrp cdrom /dev/hdc". Is just
doing chgrp enough? /sbin/MAKEDEV insists /dev/hdc should be
root:disk 0660. I don't want to edit /sbin/MAKEDEV because
it is not a conffile. Is there a possibility that some package
calls /sbin/MAKEDEV and overwrites my setting of /dev/hdc?
