The tar folks at gnu do not consider that a bug, but as a part of the

To be fair, the tar developers did fix this -- in 1.21, IIRC.
As to the original question, no, I don't think that there is any way
to "pretend" that one host/disk is the same as another. When we have
a more expressive catalog, it might be interesting to have some kind
of "redirect" that amrecover could follow when browsing the history of
a DLE -- similar to Subversion's "copy-from".
Yes. This is exactly what I think I need.
It would also help when setting up new configs if amanda would compare
IP addresses rather than hostnames when determining if different DLEs
are on the same host. You might then keep disklist containing
the_server_for_disk1 /disk1 full-tar
the_server_for_disk2 /disk2 full-tar
and so on, where "the_server_for_disk1" and "the_server_for_disk2" are
hostname aliases that are moved along with the disk, if you know what I
mean. Actually, our hosts database is set up like this already, except
there isn't one alias for each disk, but one per disk cabinet and/or
logical group of volumes.
This already works if "the_server_for_disk1" and "the_server_for_disk2"
point to different hosts, and there are no other DLEs for that host, of
course, but the idea is that they *might* be different aliases for the
same host at a certain point in time.
