The disklist is on the server. That is the file the Amanda server uses to
know which disks on which machines to back up.  The client has no knowledge
of what is supposed to be backed up, it just does whatever the server asks
it to.

If you only use dump and not GNU tar, you don't need it.  For tar it provides
the same function as /etc/dumpdates (recording when and at what level each
filesystem was last backed up).  Since the backup user doesn't normally have
permissions to create a file in /etc, root has to create it first and chown it.
I don't remember if the location and name amandates is a configure option
or not.

Also tar-specific.  I should think more generically before I reply late at
night and not assume everyone's doing things the same way I am.  If you are
using tar, that is where it keeps a list of what files were backed up when
so tar can do incrementals properly.
