I'd have preferred that Ubuntu's zfsutils be patched to attempt to load
the kernel module as needed since that change means that now any
documentation telling the user to use "zpool create" or similar zfs
commands will fail unless the user manually plays with modprobe...
That very much feels like a regression to me. I understand the reason
for not always loading the module, but having the tools attempt to load
it would have achieved the same thing without breaking every single tool
which uses the zfs tools in the process.

Title:
Please don't assume zfs module is always loaded
Status in lxd package in Ubuntu:

Status in zfs-linux package in Ubuntu:
Triaged
Bug description:
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.
ADT test of lxd (at least at 2.11-0ubuntu4[1]) shows the storage tests
are failing because "Could not determine ZFS module version." which is
printed by zfsModuleVersionGet() in lxd/storage_zfs.go. This indicates
there are pieces of code assuming zfs kernel module is always loaded
which turns out to be not true anymore.
