Finishing

lastly set your root password with passwd. And don't forget to export and unmount the pools and partitions with umount /mnt/boot, zfs umount -a, zpool export zroot. If that fails consider using the -foption to force the unmount and export and if that also fails try using the legacy unmount option with the force flag like umount -l /mnt

Your system won't boot if you forget this!!!

the system is now ready to use and bootable but it should still be configured as shown in the vanilla arch install guide to be properly usable.
