Although it seems a good policy to map a one to one slot and label, in
the long run, it may not be so.

For example, I have retired some old disks and replaced them by new
ones. The new disks would endup with the same slot numbers as the disks
they replace. But I have created new labels and marked the previous
labels as "noreuse".

That way, I still have the data on the old disks, and Amanda still keeps
a track of what is in those old labels and I could remount the disk and
access the files if needed.

(BTW, I am using an homemade changer, that splits the virtual tape across
multiple physical disks; I came to that solution many years ago when
vtape could only use one disk/directory.) 

Best regards,

Olivier
