Comment # 9 on bug 1198167 from Kenneth Aaker

I got the modprobe libafs thing to work finally.  I had to download the ssl
certificate from the OBS site directly (for a certificate with a signature of
"CF:AE:EE:5C:71:9A:E9:DE"), I then converted the certificate to a DER format,
used mokutil to enroll it, rebooted and answered the MOK boot time questions
and "enrolled" the DER key in the signature system.  Once that boot was
finished, it loaded the libafs module without complaints.

I found helpful comments in the comment section for zfs...  The URL for that is
https://build.opensuse.org/package/show/filesystems/zfs.  The helpful comments
are about a year old. The user name associated with the comments are kokeko and
