Duh!  I knew I was missing something.  Yes, that will work, you can consider
my point against /var/* moot.

Partial upgrades can be dealth with proper package scripts, and tight
dependencies I hope.

Backwards-compatibility for the early writeable fs can be dealt with by
either the INITRWFS env var (see post to pkg-initscripts-devel), or now that
we are not likely to need to move it over later, just by versioned
dependencies on the packages that need it (that make backwards compatibility
moot).
