I think we all agree that this kind of recovery *is* a killer feature.
But it isn't tied to persistance; there are various mechanisms that
could achieve this, not at all necesserily as radical.

Getting POSIX applications running isn't enough. What we need to make
sure is that UNIX users feel comfortable on the system, that it looks
familiar to them.

Of course, this still leaves quite a lot of choices about the internal
architecture of the system. However, as for user-visible changes,
radical concepts like system-wide transparent persistance are definitely
ruled out IMHO.
