So, neither the terrible NFS performance nor the weird namespacing thing 
got fixed, and Bob wanted to start migrating data, so we have gone with 
FreeBSD thanks to the two sweetest words in the English language.

I put some more details in the wiki: http://wiki.ucc.asn.au/Molmol

I've set up a GEOM mirror (RAID1) for the root filesystem. The reason for 
not using ZFS as a root filesystem is that there are reports of race 
conditions if you have multiple pools (e.g. root and space) sharing the 
same devices, which sounds reasonably nasty.
