[CentOS] Best practice preparing for disk restoring system

I'd agree with you John.  I'm trying to get away from Amanda's 
unpredictability and go back to using scripts to drive dump (for 
ext2/3/4) and xfsdump (for xfs).

Is there any easy way to tell rear to include xfsdump and dump 
capability?  If the commands are there then its trivial to restore data.

What I've done in the past is before the nightly backup write a small 
file to the root of each filesystem giving disk geometries.  You can 
then use any recovery DVD to partition and reload the OS.  If rear can 
do this for me it would be __much__ neater!
