Actually, I've used XFS since the days it was released as a port to 
Linux (and even before that, on Irix, but that's besides the point). I'm 
aware it's more fragile than Ext3 - in fact, someone here at the office 
made an XFS partition yesterday to do some tests, there was a power 
outage last night, and today that partition is corrupted.

I'll use battery backups (duh) and only put on XFS the stuff that needs 
good performance, but can be rebuilt from the master data in case 
something ugly happens. Like pretty much anything in life, it's a trade-off.
