*Don't* use k3bsetup to change any system wide information! It's (well,
last time I checked) not integrated with debian configuration mgmt. As
a result, you can change owners, groups and permissions on files all
you want, but the next time you update any of the relevant packages
they install new files with the original permissions etc.
The debianly correct way is to use dpkg-statoverride --add/--update to
change user, group and permission information for packaged files. The
relevant output from
dpkg-statoverride --list
on my system is
root cdrom 4750 /usr/bin/cdrecord
root cdrom 4750 /usr/bin/cdrecord.shm
root cdrom 4750 /usr/bin/cdrecord.mmap
root cdrom 4750 /usr/bin/readcd
root cdrom 4710 /usr/bin/mkisofs
root cdrom 4710 /usr/bin/cdrdao
I can't say offhand, why some of the files have to be group readable. I
did this several months ago and found that k3b would complain
otherwise.
Also, cdrom, not root, is IMHO the correct group to access a CD writer
on debian. Meaning among other things, that the *real* device used has
to belong to group cdrom. In my case, this is /dev/hdc for an IDE CD
writer (doesn't work with cdrdao yet!); if you're using IDE-SCSI
emulation, it's probably /dev/scd0 or a higher number.
Of course, all users who are allowed to access the CD (reading &
writing) need to be added to group cdrom:
adduser myself cdrom
I think most of what I've written could be done automatically by the k3b
package on installation. It would require a better knowledge of the
debconf system, though, than what I currently have.
