Yes, that sounds like an accurate summary. I'm not sure I follow how
/etc/fstab is related, though. Looking briefly through mkinitramfs, I
don't see where that is being used.

Good idea. Here is a more minimal way to reproduce the issue: with ZFS on root
- set 'MODULES=dep' in '/etc/initramfs-tools/initramfs.conf'
- run 'sudo update-initramfs -u'
Below is an updated patch, which finds and adds the module for each
device in the zfs pool containing the root filesystem. I've tested the
patch on Bionic and Cosmic with both zfs and ext4 root filesystems. Note
that I wasn't entirely sure if we need to handle the case where
'dev_node' is /dev/root. I'm not familiar with that setup, so I'm not
sure whether that could even apply when using zfs on root.
