user or group name, or numeric ID as argument. For system services (services run by the system service manager,
i.e. managed by PID 1) and for user services of the root user (services managed by root's instance of
<command>systemd --user</command>), the default is <literal>root</literal>, but <varname>User=</varname> may be
used to specify a different user. For user services of any other user, switching user identity is not
permitted, hence the only valid setting is the same user the user's service manager is running as. If no group
is set, the default group of the user is used. This setting does not affect commands whose command line is
