It doesn't have whitespace objects (so you can't do upper layer union mounts
with it).

: I believe the only part of the system that depends on MFS is init(8).
: If init(8) finds /dev/console missing, it creates /dev/ and runs MAKEDEV
: in it.  I have attached a patch that makes init(8) use TMPFS, instead.

Only TMPFS?  What if TMPFS fails?

Also what about config files?  No arch has it in INSTALL and only five have
it in GENERIC.
