Should, yes.

Should, yes.

We designed the head bits such that forth and lua coexist, while lua
is the default -- including for userboot. bhyveload on 12.0 will
attempt to load the guest and switch userboot if it needs to based on
the guest /boot/loader. bhyveload on 11.2 will only do forth, but that
should 'just work' because all of the forth-bits are still in /boot.
