The above layout is the one suggested in the Partition mini-howto
(http://sunsite.unc.edu/LDP/HOWTO/mini/Partition.html)  and its a good
logical setup.  I do have 1 major (for me at least) problem with the
setup, its not very friendly to 24/7 administration IMHO.  When a drive
goes (hot swappable of course), I don't wanna turn off my linux box...
but to recover what I can, umount and reconfigure hardware/os.  <shrug> 
Even if not recovering hardware, I don't want to boot just to do a full
fsck on root.  I try to leave root alone, stability is rather important.

For your setup, you may need to do the above... that or make each /usr?
/cusr? /hist tree its own partition.  No prob in Linux, there is a
logical limit, but I'm sure a dozen filesystems is not the limit.  :-) 
Or place all those tree's under another source (/usr/local/ comes to
mind) and use links.


Hope that helps.
