How did you install zfs, ie do you have zfs-dkms installed? For me the zfs modules are compiled & installed through dkms when I install a new kernel.
from ubuntu-mainline-kernel.sh.

It could be helpful if you showed some output of the script, grub, and the content of /boot.

yeah sorry.
So i ran an uninstall and reinstall, and i do see it in the install log.
But on reboot at the grub menu under 'advanced options' i get just 5.4.0-21 & 5.4.0-18

from ubuntu-mainline-kernel.sh.

OK, seems my bpool was not mounted to /boot for some reason. system was updating /boot which was now a plain directory on rpool, but at boot grub was still reading from bpool
from ubuntu-mainline-kernel.sh.

I guess as a 'mainline' kernel, this doesn't have the ZFS modules to load a root ZFS filesystem anyway?
On boot i get dumped to an initrd commandline that asks me to load the ZFS kernel modules.
Maybe yet another caveat in the README would be in order?

Ah that's interesting... i will check later it's my work computer. I
installed zfs by ticking the checkbox during the ubuntu install.

You need zfs-dkms installed if you install the mainline kernels, as those don't have zfs modules compiled in.

I've installed zfs-dkms and then 5.7.1 still no dice. Dumped to the initramfs prompt and nothing in /lib/modules//kernel/zfs+

Note that you need zfs-dkms 0.8.4 to support kernel 5.7.x , which is available most easily by updating to ubuntu groovy.
