=== 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 ==
