If, for whatever reason, you should have to reinstall the AIX OS,
then according to page 2 of the Installation Guide, the following
directories will be erased and recreated: /bin, /dev, /etc, /lib, /info,
/tmp, and /usr.  So it might save a bit of restoration time if the 
users were actually in /u.  

I've also heard rumors (as yet unsubstantiated) that a major OS 
upgrade would thrash these same directories.  I suppose something
like a move to AIX 4.x would do it.  [At the rate IBM is sending out
upgrades that'll probably be '92 :-)].
