Zitat:
When running as a service, Motion runs as the user motion and this user is automatically added to the user group of video. By only be included in this user group, when Motion is run, it will only have limited permissions. It is NOT recommended that this user get added to the sudo group. Instead, only add this user to groups that are specifically required.
On newer distributions, the above method of running a service is depreciated (but still functional) in favor of the systemctl method. Since this is not available on all the distributions which Motion is deployed, the above method is retained. Once systemctl is available on all the deployed versions, Motion will transition to systemctl as the service method. For users that wish to systemctl rather than the above method, a motion.system file is included in the source code.
Nun Ubuntu ist neuer bzw nutzt systemd...
