It is a lot less of a hack than what went before.
The only other option would be an actual (working) union mount,
and that has much bigger problems - not to mention needing
process specific mount tables!

OTOH I do wish the 32bit/64bit compatibility had been done as part of
the '64bit' port - so that the 64bit userspace doesn't have to rename
anything from the 32bit version - giving you a userpace that can
(at least in theory) boot either a 32bit or 64bit kernel.
