66 | ||
67 | <para><command>systemd-sysusers</command> creates system users and | |
68 | groups, based on the file format and location specified in | |

72 | <para>If invoked with no arguments, it applies all directives from all files |
73 | found in the directories specified by | |
74 | <citerefentry><refentrytitle>sysusers.d</refentrytitle><manvolnum>5</manvolnum></citerefentry>. | |
75 | When invoked with positional arguments, if option | |
76 | <option>--replace=<replaceable>PATH</replaceable></option> is specified, arguments | |
77 | specified on the command line are used instead of the configuration file | |
78 | <replaceable>PATH</replaceable>. Otherwise, just the configuration specified by | |
79 | the command line arguments is executed. The string <literal>-</literal> may be | |
80 | specified instead of a filename to instruct <command>systemd-sysusers</command> | |
81 | to read the configuration from standard input. If only the basename of a file is | |
82 | specified, all configuration directories are searched for a matching file and | |
83 | the file found that has the highest priority is executed.</para> | |

101 | <term><option>--replace=<replaceable>PATH</replaceable></option></term> | |
102 | <listitem><para>When this option is given, one ore more positional arguments | |
103 | must be specified. All configuration files found in the directories listed in | |
104 | <citerefentry><refentrytitle>sysusers.d</refentrytitle><manvolnum>5</manvolnum></citerefentry> | |
105 | will be read, and the configuration given on the command line will be | |
106 | handled instead of and with the same priority as the configuration file | |
107 | <replaceable>PATH</replaceable>.</para> | |
108 | ||
109 | <para>This option is intended to be used when package installation scripts | |
110 | are running and files belonging to that package are not yet available on | |
111 | disk, so their contents must be given on the command line, but the admin | |
112 | configuration might already exist and should be given higher priority. | |
113 | </para> | |

115 | <example> | |
116 | <title>RPM installation script for radvd</title> | |
117 | ||
118 | <programlisting>echo 'u radvd - "radvd daemon"' | \ | |
119 | systemd-sysusers --replace=/usr/lib/sysusers.d/radvd.conf -</programlisting> | |
120 | ||
121 | <para>This will create the radvd user as if | |
122 | <filename>/usr/lib/sysusers.d/radvd.conf</filename> was already on disk. | |
123 | An admin might override the configuration specified on the command line by | |
124 | placing <filename>/etc/sysusers.d/radvd.conf</filename> or even | |
125 | <filename>/etc/sysusers.d/00-overrides.conf</filename>.</para> | |
126 | ||
127 | <para>Note that this is the expanded from, and when used in a package, this | |
128 | would be written using a macro with "radvd" and a file containing the | |
129 | configuration line as arguments.</para> | |
