Synopsis

Parameters

Parameter Choices/Defaults Comments
enabled
boolean
    Choices:
  • no
  • yes
Enable or disable the service, independently of *.preset file preference or running state. Mutually exclusive with preset. Will take effect prior to state=reset.
name
string / required
Name of the service to manage.
preset
boolean
    Choices:
  • no
  • yes
Enable or disable the service according to local preferences in *.preset files. Mutually exclusive with enabled. Only has an effect if set to true. Will take effect prior to state=reset.
state
string
    Choices:
  • started
  • stopped
  • reset
  • restarted
  • reloaded
started/stopped are idempotent actions that will not run commands unless necessary. restarted will always bounce the service. reloaded will send a SIGHUP or start the service. reset will start or stop the service according to whether it is enabled or not.
user
boolean
    Choices:
  • no
  • yes
Run system-control talking to the calling user's service manager, rather than the system-wide service manager.
