(Debian/Ubuntu Example)

1. Copy this start script to /etc/init.d/ethminer (above) :
   https://gist.github.com/bmatthewshea/9a062c092fd673318f8d208ce44f4f51

2. (optional, but recommended) Copy this script to /etc/default/ethminer and edit it (your settings).
   https://gist.github.com/bmatthewshea/be95abefb0d535afeba7aa0cb680fa08

3. Update top portion of script or preferably update/the defaults file (#2).

4. Execute:

# user you run this under - the log area needs to be owned by that user ('ubuntu' user example):
sudo mkdir /var/log/miners && sudo chown ubuntu:adm /var/log/miners

sudo chown root:root /etc/init.d/ethminer && sudo chown root:root /etc/default/ethminer
sudo chmod 755 /etc/init.d/ethminer && sudo chmod 644 /etc/default/ethminer
sudo update-rc.d  ethminer defaults
sudo update-rc.d  ethminer enable
sudo systemctl daemon-reload

And finally, start the miner:
sudo service start ethminer
or
sudo systemctl start ethminer.service

5. Monitor:
   tail -f /var/log/miners/ethminer.log
   (You can check output..)
   Please see this: https://gist.github.com/bmatthewshea/6bad5242dbf270ef881c033918b947c0 for a way to monitor this service for inactivity.

6. Stop/Start/Restart with:
   sudo service ethminer stop
   or
   sudo systemctl stop ethminer.service

FYI, If one is not using the optional settings, one also has to set the "FSERVERs" variable in the start script, otherwise the ethminer script fails

@aptalca - Thanks. I re-added it. Typo. Better off using the '/etc/default/', file though..

Right before step 5 you say use:
sudo service start ethminer
it should be
sudo service ethminer start

Otherwise, this is great! I did make some modification to my monitor such that it checks temps as well and stops if too hot and restarts if too cold. I found some random errors would not cause the miner to stop writing to the log file, even though it clearly stopped mining and the GPU would get cold.
