To timidly go where many have gone before

Woohoo! We can now do a native boot from ZFS, at least for x86 servers. Live Upgrade doesn't support this yet, and since I use Live Upgrade on both my home system and my laptop, I thought I'd wait a while before giving this a go. But Live Upgrade with ZFS will mostly just involve taking a snapshot and cloning it, so one could hack something together to get similar functionality. Here is someone's experience of having done just that. (Note that this involves using BFU and not doing an OS upgrade like you'd do with Live Upgrade, but it's still pretty interesting.)
