[Users] custom nfs mount options

[Alex Leonhardt]

So I've tried some bits Itamar asked me to - however, still get the same
mount options shown.

I tried "service vdsmd reconfigure; service vdsmd restart" - the mount for
HV03:/vmfs/data should now have the new mount options, but no luck.

Anyone time to help ?

Alex
