yea, efibootmgr -k is what's needed. You'll need to specify the partition
to boot off of. That's the ideal solution.

These might work. bootme is only documented in the BIOS loader man
page...

There's also an unsupported, may go away in the future gptboot.efi
that you can use if you really must use this setup.. We use it for bootable
USB drives at work, but if it doesn't work for you, I'm not sure I'd fix
bugs
in it.

However, we're moving to ZFS only, and we've found ZFS BEs to be way
more flexible and will be the way of the future. As such, I've stopped
maintaining gptboot.efi and will likely remove it in the future.
