Well, next thougt: maybe it's kinda chicken'n'egg problem: if you have
build machine, made there a buildworld, and then export both /usr/src and
/usr/obj via read-only NFS, you have exactly the same problem...

Luckily enough, 'build installworld' is not quite frequent task to do ;-)
Moreover, UPDATING tells us we should do this in single-user mode so
noexec harms noone but you The Machine Superior ;-)

Sincerely,
