Hi,

I suspect 4th vs. lua has no impact here, given the output shown --
can you throw one of the installer images [0] on some removable media
and give that a shot for booting? If that works, we can explore UEFI
variables from there.

efibootmgr will only work on a successful UEFI boot, unfortunately- if
we didn't make uefi loader -> kernel transition, then we don't have
access to runtime services.

Thanks,

Kyle Evans
