Package: nfs-kernel-server
Version: 1:1.2.8-9
Severity: grave
Justification: renders package unusable

Relatively new system and I'm trying to get nfsd working, but it fails.

After looking at journalctl, it seems that the nfsd module can not be loaded:

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
