Bug#798314: systemd: Systemd waits 30 minutes to shut down because of NFS share

[Javier Ayres]

I edited the wpa_supplicant service as you suggested but the issue is still
present. I've also found that the behavior is not consistent, sometimes it
waits 90 seconds and sometimes it waits 30 minutes (even after changing the
fstab entry).
