the ramfs trick will not work if you have a standard
plan 9 network with >1 machine.

if you used /lib/namespace instead, things would be better.
unfortunately since union mounts are not deep, this would
be a very difficult thing to construct.

i still think it's a mistake to think that not overwriting things
is a panacea.  the essential problem in this case is that is
is difficult (if not impossible) to test the tuple (original version
upgrade version, base system).
