How do I use the --numeric-owner flag which makes tar not lookup uid/gid

What does amanda use while estimating a volume? I have /var/spool/mail
55 GB big (EXT3) with 1944656 inodes used and it lasts an eternity for
amanda to do the volume estimation. How can I speed it up? Not only the
estimation, the dump process too.
This server has to be backuped and it's mapped on LDAP. I'm trying to
avoid a huge amount of LDAP queries (which I guess slow amanda down)
During estimate there are now LDAP queries, as tar only stats() each
file to get the size. No speed increase to be expected here from such
a flag.
In amanda 2.4.5 (still beta, but in use already by some people) there
is a possibility to base estimates on historical data. Not as accurate
as doing a real dry run, but surely fast.
TO add the --numeric-owner flag, you could take the tar-wrapper path:
compile amanda with:
./configure ... --with-gnutar=/usr/local/bin/amgtar
and create a shell script amgtar that inserts the flag in the arguments
before calling the real gnutar.
