boot/pxeboot broken in freebsd-12?

[James Snow]

Hello -stable,

We have a PXE environemt that builds FreeBSD-11 boxes. We've started
to dip our toes into the 12.x waters, but have had trouble getting
FreeBSD-12 to pxeboot. It would crash and burn like so:

    Startup error in /boot/lua/loader.lua:
    LUA ERROR: cannot open /boot/lua/loader.lua: device not configured

On a whim, I pulled the boot/pxeboot binary from our FreeBSD-11
environment into the new FreeBSD-12 environment, and PXE clients started
coming right up.

Is FreeBSD-12's pxeboot broken or have I missed something?
