shm refclock

[Paul Theodoropoulos]

gpsd needs to start before ntpd when using shm refclock.

Here's my systemd startups:

GPSD:
Description=GPS (Global Positioning System) Daemon
Before=timeservice.service
Requires=timeservice.service

[Service]
Type=oneshot
EnvironmentFile=-/etc/default/gpsd
ExecStart=/usr/local/sbin/gpsd $GPSD_OPTIONS $OPTIONS $DEVICES
ExecStartPost=/usr/local/bin/sched.gpsd
ExecStartPost=/bin/sleep 5
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

Timeservice:
[Unit]
Description=Manage time service daemons
BindsTo=gpsd.service

[Service]
Type=oneshot
ExecStart=/etc/init.d/timeservice start
ExecStop=/etc/init.d/timeservice stop
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

If I restart my RPI, it comes up fine with those startups.
