the procedure described here is like doing FLAR by hand, so it'll
probably be useful in quite a lot of situations, especially with the
frequent genunix livec

Not yet, but this has been discussed here before. It is something I

Another approach is to make a new virtual disk and attach it as a mirror.
Once the silver is complete, detach and destroy the old virtual disk.
Normal procedures for bootable disks still apply.
This works because ZFS only silvers data.

I haven't had a chance to test this, but he had documented a
way to shrink a pool in VBox, described here:
