Same problem here:
- I'm building FreeBSD head on a builder machine, and NFS mounting its
/usr/src and /usr/obj to 4 others

Results:
- 2 of them, UEFI+ZFS machines works great ((Thinkpad T420 and AMD Epyc
with Tyan motherboard)
- 2 of them, BIOS+UFS machines meet this "can't find /boot/ua/loader.lua"
(HP microserver and PC Engines APU2)

I had to boot from an USB stick, mounting the system partition and "cp
boot/loader_4th.old boot/loader".
