Comment 76 for bug 1590799

Thanks Maarten for the detailed write up. I was able to follow it precisely but to no avail. I believe I must be suffering from other problems. What looks like the relevant section in the journalctl output looks like so:

<SNIP>

So there is something problematic with the nfsd filetype since I also get this problem

~$ sudo mount -t nfsd nfsd /proc/fs/nfsd
mount: /proc/fs/nfsd: unknown filesystem type 'nfsd'.

Which somehow means that the nfsd filetype which requires some kernel module (Provided by: nfs-kernel-server_1.3.4-2.1ubuntu5_amd64 ???) isn't there.
