default settings break root on zfs after kernel updates #28

See https://github.com/openzfs/zfs/issues/10355 . REMAKE_INITRD='yes' needs to be added to /etc/dkms/zfs.conf to prevent breakage upon kernel updates, making it impossible to boot. Took a lot of time to debug and fix, annoying.

Also, the grub changes make it impossible to boot into hetzner's rescue mode, requiring a support ticket to change boot order and make it working again. Please fix this.

Unrelated, but there's a stray 18.04 variable in the script:

can you elaborate this point? on which OS have you experienced it?

I also just ran into the issue of a non-booting system (Debian Bullseye) after an upgrade of linux-image-amd64. Maybe this will keep the doctor(rescue-shell) away in the future.
