I wouldn't say it's necessary, especially in a small cell, but it  
does make things easier.

The other suggestion I'd make is to put /vicep* on external disks  
(preferably RAID...).  This makes upgrades almost trivial:  shut down  
old fileserver, unplug disk from old machine, plug into replacement,  
boot.  (Well, with a hostname change for the new machine, presumably.)
