That's correct I believe, yes.

Wait, so it's persisting any changes you made to the target drive?
That sounds quite cool actually, and I misunderstood the original
post.  Concretely with your change, if I've connected to a wireless
network with NetworkManager, that would get saved in the target
drive's configuration in gconf and be there next time I boot?

I know with the live images one problem we have is that data can sort
of randomly disappear if you're running close to the memory limit; if
we go with your architecture we should probably special-case things
like ~/.gconf so say the Firefox http disk cache doesn't blow away
your wireless config.
