<title>Description</title>
<para><filename>systemd-verify</filename> will load unit files and
potentially print warnings if any errors are detected. Files
specified on the command line will be loaded, but also any other
units referenced by them.</para>
<para>This command works by prepending the directories for all
command line arguments at the beginning of the unit load path.
This means that all units files found in those directories will
be used in preference to the unit files found in the standard
locations, even if not listed explicitly.</para>
<para>The following errors are currently detected:</para>
<itemizedlist>
<listitem><para>unknown sections and directives,
</para></listitem>
<listitem><para>missing dependencies which are required to start
the given unit,</para></listitem>
<listitem><para>man pages listed in
<varname>Documentation=</varname> which are not found in the
system,</para></listitem>
<listitem><para>commands listed in <varname>ExecStart=</varname>
and similar which are not found in the system or not executable.
