[-- Attachment #1 --] I had thought it would be necessary in order to point the loader at the correct ZFS partition (linux does require this), but apparently loader figures out what partition it should be dealing with just fine. I don't doubt it would be a good change, and loader could use some refactoring IMO, but I'd like to keep the changesets as small as possible.
