HowTo:Install Sabnzbd, Sickbeard & CouchPotato on ReadyNASO6

wizzard: did you solve the CP problem?

I just installed Sabnzbd and Sickbeard using this guide and it all went fine.
However I have some issues regarding CP.

I followed the steps above but when starting I have:

root@Ultra:/usr/share# /etc/init.d/couchpotato start
/etc/default/couchpotato not found using default settings.
[....] Starting couchpotato (via systemctl): couchpotato.serviceWarning: Unit file of created job changed on disk, 'systemctl --system daemon-reload' recommended.
Job failed. See system journal and 'systemctl status' for details.
 failed!

My /etc/init.d/couchpotato looks like this:

# Run CP as username
RUN_AS=${CP_USER-couchpotato}

# Path to app
# CP_HOME=path_to_app_CouchPotato.py
APP_PATH=${CP_HOME-/usr/share/couchpotatoserver}

# Data directory where couchpotato.db, cache and logs are stored
DATA_DIR=${CP_DATA-/usr/share/couchpotatoserver}

# Path to store PID file
PID_FILE=${CP_PIDFILE-/var/run/couchpotato.pid}

# path to python bin
DAEMON=${PYTHON_BIN-/usr/bin/python}

Any ideas?

EDIT: running it manually works:
/usr/share/couchpotatoserver/CouchPotato.py --quiet --daemon
and it seems CP is using the settings in ~/.couchpotato#

EDIT2: I ended up using another init.d script and now it´s working
