So do it, just don't try to push FreeBSD to use it in base.

Couldn't agree more: when I did run jails, I would just compile a static binary and jail that process (of course devd made that a bit of a pain, but eventually you can figure out what's needed to have a single statically-linked binary jail without the bloat). -- Igor M.
