An update to this problem:
When I run amanda as root user this does not happen.
I wonder why, amanda user has all rights on tape devices and loader device (it
is in sys group). It is also the owner of configuration, debug, log and so on
directories, the "amanda" group is allowed to execute every single binary from
amanda directory.
Again, it does work when no barcode reading is involved, what is so special in
chg-scsi to require root rights when it has to access barcode reader ?
