Hi,

when booting -current (arm64) after building world & friends and rebooting,
the beastie menu shows "Loader needs to be updated".

I presume this to be gptzfsboot because the system is root-on-zfs.

The issue I'm having is that I can't see in the manpage how to actually
update it.

The system uses GELI encryption for zfs. i don't want to break this.
