hi,
no answer yet, but after some experimenting:
boots diskless:
	if no local disk - dah
	if local disk and no EFI partition
	if local disk has the above but no valid root partition
and finally if root partition and efi but no bootx64.efi ( i just move it to bootx64.efix)

thanks,
	danny
ps: i guess i forgot to mention that the host is running in bhyve (14.3)
pass: it’s now alpha-5
