There's a few funny things / clues here and there on the Lion recovery disk "Systems" - that indicate you can save your settings between boots. A very light smattering of persistent settings etc. Beyond that.. Does anyone know if you can enable the root account or if there is an admin password etc. on these boot drives? It would kinda be nice to be able to look around when booted to these things, possibly see what's going on under the hood etc.. Also, it might open the door to being able to SSH to the machine, which would definitely come in handy during tough installs, or other strange circumstances.
