Interestingly, two of you have reported this same issue in the last
couple of days, although I have not seen it personally on my boxes.

I think your diagnosis is more-or-less correct.  The target_scsi_id is
the problem, and it was a good guess to try putting "/dev/cdrom" into
that field.  Unfortunately, Cedar Backup doesn't currently allow the
target_scsi_id to be a device path -- you have to put a valid SCSI id
into that field.  Cedar Backup considers the following three SCSI id
forms valid:

      scsibus,target,lun
      ATA:scsibus,target,lun
      ATAPI:scsibus,target,lun

Try using these commands to see if either finds your CD writer:

       cdrecord -scanbus dev=ATAPI
       cdrecord -scanbus dev=ATA

If either command does find your writer, you can use one of the
alternate SCSI address forms (i.e. "ATA:1,0,0") in Cedar Backup
configuration.  This is what I do on my master (running Debian sarge).

If this does *not* work for you, let me know, and I'll try to release
a new Cedar Backup version soon that allows you to specify your device
differently.  (I'm still trying to decide what form this change will
take.)

Incidentally, can you tell me whether you have the package 'wodim'
installed, or 'cdrecord'?  Debian recently got rid of cdrecord in
favor of wodim, and I'm not sure which package Ubuntu 6.06 would be
using.

       dpkg --get-selections | grep -i wodim
       dpkg --get-selections | grep -i cdrecord

It's possible that wodim (being essentially an old version of
cdrecord) does not work the same as cdrecord with respect to ATA and
ATAPI devices -- and this could explain the sudden emergence of this
problem among Debian and Ubuntu users.

Thanks!
