Re: boot error: zfs + luks + grub

[James]

Thanks Andrei, this helped. I rebuilt my initramfs and updated grub.
Definitely a step in the right direction.

Now when I reboot my system GRUB will prompt me for a master key. I provide
the password and successfully unlock (presumably) one of the crypto disks.

It then prompts me for another password. It says that it opens slot 0, but
then GRUB immediately fails.

Please see attached screenshot.

Any thoughts on why this is happening?
