Yes please.

Except that this is only guaranteed to work if the build machine and
target machine are running the same kernel and the build machine's
userland is executable on the target machine.  (This is because the
first part of the buildworld builds tools against the current
userland).

As an example, if my build machine is a PIII (build with CPUTYPE=p3) then
I can't mount src/obj onto an i486 and run installworld - it will try to
execute non-i486 instructions.
