If it is then how do you explain the statistically significant
correlation between intra-disk partitions and diskfull trouble tickets?
Partitions may work well for inter-disk partitions (inter != intra) but
if they made systems administration easier you'd think we would see them
implemented on raid-based NAS and SAN fileservers.  We don't because they
