Bug Description

If you install Xen on your Ubuntu 20.04 system with ZFS, the system becomes unbootable because the adjustments made by Canonical to GRUB by providing 10_linux_zfs to override 10_linux aren't done to 20_linux_xen as well. I'm not asking for the same level of zys integration with a Xen system, I'm just asking for a bootable system. The following patch was posted to the GRUB mailing list and it would be good to backport it so that people don't experience systems that don't boot.

Other people have experienced this as well based on https://askubuntu.com/questions/1271948/ubuntu-20-04-with-zfs-root-fails-to-boot-after-installing-xen
