systemctl boot message

[notoneofmy <notoneofmyseeds@gmx.de>]

I'm trying to solve an NFS issue.

The problem is that the client, Debian Jessie, won't mount the remote 
file system; the NFS server directories specified in fstab.

But this can be done in Terminal as root.

Errors during boot:
systemctl status (and then the directory of the mount point is given)
DEPEND: Dependency failed for Remote File Systems
And then messages about the mounts failed.

After boot, clicking on the grayed-out mount points in the window 
manager gives:
"only root can mount" (and then the directory of the mount point is given)

An fstab entry is like this:
10.0.0.6:/mnt/MoviesNsuch/music /home/sunny/nfs/music nfs 
rw,rsize=32768,wsize=32768,_netdev, no_root_squash,async,hard,intr 0     0

Thanks for your considered thoughts in helping me resolve this matter.
