With linux, I would agree, and indeed have several machines set up in
this very fashion.

However, FreeBSD appears to make too many assumptions about what resides
where to make this a viable option, such as only booting from the 'a'
partition, and then subsequently mounting it as / regardless of the
contents of the fstab.

Though, you might be able to get away with it by creating a fake root
and init in mfsroot or elsewhere that contains just enough logic to load
modules, build arrays, and then mount the real root and exec the real
init. Sounds like a pain, though.
