I couldn't spot anything looking through the logs;  I assume the last installation
was no further back than Nov/Dec or worst around EuroBSDCon time but possibly also
from Feb or Mar.  Problem is that I also used to netboot the host for a while but
the NFS export has been updated too often in the meantime.


Given there was nothing obvious with bhyve I just took a BHYVE_UEFI.fd from an old
(yet untouched) installation and just pointing to that makes things work again
(well it tries to PXE now); no idea beyond yet as I used a simple dummy command
to test.  Ok, booted the real thing and both PXE and passthru work.

The machine I took it from says it once got edk2-bhyve-g202308_5 installed and
checksums are still fine.

I assume this may be a ports issue then, or some interface changed and we are
not properly populating things the new way?
