To my knowledge it did :) We allocate 20g for our root zfs pool which
is good for an LU or so. We alternate between them and clean installs.

Roughly how long

The LU probably took 45 minutes to an hour. I didn't install any patch
bundles on top of it, so installing those (via PCA) took another 15-30
minutes.

Our clients (also s10u7; 1.4.10) are given a 2g AFS cache via a zfs
vol. Atime turned off for performance.
