OK, that's helpful to know I haven't missed the obvious.

NFS root is the next thing on my list to figure out. :) I'd like to get
it to the point of only needing /boot on iSCSI, at least until btrfs
lands. I should probably mount it sync too, just in case.
Does Xen deal with a device going away and coming back with the same
name? Either automatic or via hotplugging would be effective. I'm
using /dev/disk/by-path/ names so they should line up correctly at least.
