@Benjaminrenz the reason for this behavior is that the service uses
Type=oneshot(the service will be in the activation state unil the command exits, the start command will wait for activation to complete).Removing that directive will use the default
simpletype (which IMO is more correct). Removing the-Bwill allow the service to be started multiple times without the scrub compleng (which will cause the service to fail).
