Document how to use systemd instead of supervisord

[clochix]

On systems already running systemd, users may prefer to use it instead of supervisord. We should provide a sample configuration file aned explain how to use it.

(only in the “step by step” page, or for avery installation method?)

[Unit]
Description=Cozy Controller

[Service]
Environment=NODE_ENV=production
Environment=USE_SYSLOG=true
Environment=WEBOOB_PYTHON_PATH=/usr/share/cozy-weboob/lib/python2.7/site-packages
Environment=WEBOOB_DIR=/usr/share/cozy-weboob/lib/python2.7/site-packages
ExecStart=/usr/bin/cozy-controller

[Install]
WantedBy=multi-user.target

[ArchangeGabriel]

As an external user, and from an user support point of view, I would say only offer this possibility in the “step-by-step” page (it’s now in the Arch wiki too for what it’s worth, btw both are obviously very similar).

Or decide to use systemd everywhere it’s available.
