This method of updating the ESP is no longer recommended for new 12.x
installations -- we now more carefully construct the ESP with an
/EFI/FreeBSD/loader.efi where loader.efi is /boot/loader.efi. You will
want to rebuild this as such, and that may fix part of your problem.

Was vfs.root.mountfrom set correctly? My completely uneducated guess
is that it likely wasn't and we couldn't locate the zpool.cache -- the
value of vfs.root.mountfrom should basically match the currdev format
here, except without a trailing colon.
