This is where my knowledge of Linux falls short.

is the package you installed for ZFS a DKMS kernel module, or a binary one?

In both Fedora and Silverblue I find the same, ZFS-related files, under /usr/sbin/

Also, ztest does something

<span style="color:#323232;">verifying concrete vdev 0, metaslab 11 of 12 ...
</span><span style="color:#323232;">loading concrete vdev 0, metaslab 11 of 12 ...
</span><span style="color:#323232;">verifying concrete vdev 0, metaslab 11 of 12 ...
</span>

I assume, therefor, that OpenZFS exists, however the kernel is not loading the related module.
Binary, library or something else - how can I tell?
