=== Troubleshooting ===
* Naughty telescope claims "Trying to contact centrald" and rts2-mon won't start:
sudo /etc/init.d/rts2 start
* Certain subsystems don't wake up:
sudo /etc/rts2/start-rts2
* Certain subsystems don't wake up with start-rts2 command above:
ps -Af | grep rts2
sudo killall <relevant process>
where <relevant process> could be:
rts2-teld-sitech-altaz - alt & az motors
rts2-sitech-focmirror - M2 and M3
rts2-rotad-sitech
rts2-httpd - for thrift?
rts2-cupola-saao - dome
Then restart:
sudo <relevant process>
* Derotators still don't wake up with start-rts2 command above:
sudo rts2-rotad-sitech -f /dev/derotators --defaults-der1 -=/etc/rts2/D1.ini --defaults-der2 -=/etc/rts2/D2.ini
