Comment 11 for bug 1741081

zfs-load-module.service seems to have a Requires on itself? That has to be wrong.

Also, zfs-import-cache.service and zfs-import-scan.service need an After=zfs-load-module.service. They're not getting one automatically because of DefaultDependencies=no (which seems appropriate here, so leave that alone). Scott, can you try this? I think it will fix your issue, since zfs-mount.service already has After=zfs-load-cache.service and After=zfs-load-scan.service.

The proposed package, with the changes above should fix the issue I'm reporting.

However, LP #1672749 says, "Since zfsutils-linux/0.6.5.9-4, zfs module is not automatically loaded on systems that no zpool exists, this avoids tainting everyone's kernel who has the package installed but is not using zfs." Is this still an important goal? If so, wasn't that lost with ubuntu-load-zfs-unconditionally.patch? Or perhaps something is keeping zfs-import-scan.service from being enabled by default?
