Fstab nfs mount now needs nfsver=3

I’m running software release 2017.10-1 on my Vero 4k and since this update my nfs mount via the fstab stopped working. Even mounting from the command line failed:

root@vero4k:~# mount -t nfs nasty.lan:/share/movies /mnt/movies
mount.nfs: an incorrect mount option was specified
root@vero4k:~# mount.nfs -s -v nasty.lan:/share/movies /mnt/movies 
mount.nfs: timeout set for Fri Nov  3 00:04:13 2017
mount.nfs: trying text-based options 'sloppy,vers=4,addr=,clientaddr='
mount.nfs: mount(2): Invalid argument
mount.nfs: an incorrect mount option was specified 

After adding nfsvers=3 to fstab everything works again. My fstab without nfsver=3 worked fine before this update.

There have not been any NFS changes in the update.


Ok, that is strange. I haven’t updated the OS in a while though so it could have been an earlier version.
