Or maybe we could have 2 scripts to unmount network shares:
- one that is run before NM is stopped, and that umounts every NFS/CIFS
mount except /usr
- and the other that is still run after NM stops, and that umount /usr
if it is on NFS

This way we still support /usr over NFS, the only condition is that the
interface used to mount /usr must not be handled by NM, but this looks
like a safe assumption as NM cannot be started without /usr anyway, so
no one would could rely on /usr being mounted using a NM-managed interface.
