<para>If a command is run as transient service unit, it will be
started and managed by the service manager like any other service,
and thus show up in the output of <command>systemctl
list-units</command> like any other unit. It will run in a clean
and detached execution environment. <command>systemd-run</command>
will start the service asynchronously in the background and
immediately return.</para>
<para>If a command is run as transient scope unit, it will be
started directly by <command>systemd-run</command> and thus
inherit the execution environment of the caller. It is however
managed by the service manager similar to normal services, and
will also show up in the output of <command>systemctl
list-units</command>. Execution in this case is synchronous, and
execution will return only when the command finishes.</para>
