Updateds zfs pool from OpenZFS release 2.2.0 and ZFSBootMenu can not boot from pool, what now?

As mentioned here, ZFSBootMenu prior version 2.2.1 is not able to boot a zpool once updated.

It took me some time and a few tries to understand that the solution is incredible simple.

Based on the official documentation, all you have to do is to:

  • Boot from a live iso like archzfs.iso
  • Mount your EFI-Partition
  • curl -LJO
  • cp zfsbootmenu*.EFI /efi/EFI/ZBM/vmlinuz.EFI
  • Umount your EFI-Partition
  • Reboot

I've updated the archzfs iso build script to automatically create a iso file with the latest ZFSBootMenu pre-shipped.
