Okay, I think I understand (some <G>).
I need to use the cdrom entry as a model but change cdrom to tape or
auto_ changer0 - correct.
I've found out that the backup software tries to find an sg device for
the library and then create a symlink to it - which doesn't work under
devfs. I've got the library working by using /dev/sg2 as the device
instead of auto_changer0.
So /etc/devfsd.conf is where we create these links that we want to have
and the copy lines make sure they are persistant??
