=== Upgrade the bootloader ===
We need to update the bootloader, otherwise the system [https://lwn.net/Articles/852586 will stop booting eventually] (but not immediately). I think this is only necessary after <code>zpool upgrade</code>, and <code>zpool upgrade</code> used to warn us about this, but apparently not anymore? (Maybe it's related to the switch to OpenZFS — unclear.) Presumably you can do this after booting into the new system, but before <code>zpool upgrade</code>.
==== BIOS ====
gpart bootcode -b /mnt/boot/pmbr -p /mnt/boot/gptzfsboot -i 1 da0
gpart bootcode -b /mnt/boot/pmbr -p /mnt/boot/gptzfsboot -i 1 da2
Of course, if you already booted into the new system, these become:
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da2
==== EFI ====
pkg -c /mnt update
pkg -c /mnt upgrade
== Activate the new BE ==
