If you don't need a jail to spoof uname, as others posted, you can
installworld into a chroot and build everything you want there using
Joerg's spiffy pbulk.  That's what I'm doing on pkgbox now; I can hand you
my somewhat terse notes if you want.  It would be relatively easy to set
up the configuration you're talking about.
