Talk to the service manager of the calling user, rather than the service manager of the system. Talk to the service manager of the system. This is the implied default. Execute the operation remotely. Specify a hostname, or a username and hostname separated by @, to connect to. The hostname may optionally be suffixed by a port ssh is listening on, separated by :, and then a container name, separated by /, which connects directly to a specific container on the specified host. This will use SSH to talk to the remote machine manager instance. Container names may be enumerated with machinectl -H HOST. Put IPv6 addresses in brackets. Execute operation on a local container. Specify a container name to connect to, optionally prefixed by a user name to connect as and a separating @ character. If the special string .host is used in place of the container name, a connection to the local system is made (which is useful to connect to a specific user's user bus: --user --machine=lennart@.host). If the @ syntax is not used, the connection is made as root user. If the @ syntax is used either the left hand side or the right hand side may be omitted (but not both) in which case the local user name and .host are implied. Execute operation on a capsule. Specify a capsule name to connect to. See capsule@.service5 for details about capsules.
