So, what now?  It *still* doesn't see the disk in the local machine.
And amrecover is *still* trying to talk to "localhost".

[root@backup root]# amrecover

There has to be some other config somewhere...

amanda is almost certainly using the resolver on the machine.  These
little programs just make the C calls and rturn results.  dig will do
that, too.

That Makefile worked just fine... :-)
