Subsequent boots succeed ☑ without the need to disconnect the non-boot drive. 

Now I see e.g. <https://www.freebsd.org/cgi/man.cgi?query=uefi(8)> and
<https://www.freebsd.org/cgi/man.cgi?query=efibootmgr(8)>, however I was not
previously aware of the need to manually mount and update a boot partition – I
mentioned boot failures a few months ago, no-one dropped a hint re: updating.
So I'll leave this open as a documentation bug. 

We have <https://docs.freebsd.org/en/books/handbook/zfs/> Chapter 20 for ZFS
and <https://docs.freebsd.org/en/books/handbook/cutting-edge/> (not entirely
cutting edge) Chapter 24 for updating and upgrading FreeBSD. 

I can't find a hint about BOOTx64.efi anywhere in the handbook. Maybe it
belongs near the head of Chapter 24, as example of what's _not_ updated when an
update is performed …

Thanks
