I have some goodish news... I back up my / mirror to my /mnt/backup mirror 
nightly... that means I have last nights state saved... everything not 
in  /home is archived.  I am going to dig through it to see if i can find a 
copy of what SuSE thought my raidtab was.  If anyone has a clue, lemme know.

not to self, remark out all archiving cron jobs
