My /dev/root isn't a sym link but a normal device file.  No LVM in use
either.  I'm trying to figure out why amanda's backing up /dev/root instead
of simply /.  Here's the lines from disklist:
Sakai           /               comp-root       1
Sakai           /boot           comp-root       1
Sakai           /usr/local      comp-root       2
Sakai           /var            comp-root       2

[10:00am] cmarble@sakai (/dev): ll sda1 sda2 sda root
brw-r-----  1 root disk 8, 2 Oct 26 04:34 root
brw-rw----  1 root disk 8, 0 Oct 26 04:34 sda
brw-rw----  1 root disk 8, 1 Oct 26 04:34 sda1
brw-rw----  1 root disk 8, 2 Oct 26 04:34 sda2

Lastly lines from sendsize and sendbackup showing successes and failures:

You see that amanda is asking for information on /dev/root rather than simply /
