Comment # 46 on bug 1116625 from Jiri Slaby

I think the bug still persists. Last time I saw this with
NetworkManager-1.28.0-1.1.x86_64

installed on 12/18. I edited /etc/NetworkManager/dispatcher.d/nfs on 12/21:
>                # Only unmount it when the type is nfs or nfs4
>                if [ "$FS_TYPE" == "nfs" -o "$FS_TYPE" == "nfs4xx" ]; then

The condition is inverted (by !), I think:
'/x-systemd.automount/!d'
