- <para><command>systemd-tmpfiles</command> uses the configuration
- files from the above directories to describe the creation,
- cleaning and removal of volatile and temporary files and
- directories which usually reside in directories such as
- <filename>/run</filename> or <filename>/tmp</filename>.</para>
-
- <para>Volatile and temporary files and directories are those located in <filename>/run</filename>,
- <filename>/tmp</filename>, <filename>/var/tmp</filename>, the API file systems such as <filename>/sys</filename> or
- <filename>/proc</filename>, as well as some other directories below <filename>/var</filename>.</para>
-
- <para>System daemons frequently require private runtime
- directories below <filename>/run</filename> to place communication
- sockets and similar in. For these, consider declaring them in
- their unit files using <varname>RuntimeDirectory=</varname> (see
- <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>
- for details), if this is feasible.</para>
+ <para><filename>tmpfiles.d</filename> configuration files provide a generic mechanism to define the
+ <emphasis>creation</emphasis> of regular files, directories, pipes, and device nodes, adjustments to
+ their <emphasis>access mode, ownership, attributes, quota assignments, and contents</emphasis>, and
+ finally their time-based <emphasis>removal</emphasis>. It is mostly commonly used for volatile and
+ temporary files and directories (such as those located under <filename>/run</filename>,
+ <filename>/tmp</filename>, <filename>/var/tmp</filename>, the API file systems such as
+ <filename>/sys</filename> or <filename>/proc</filename>, as well as some other directories below
+ <filename>/var</filename>).</para>
+
+ <para><command>systemd-tmpfiles</command> uses this configuration to create volatile files and
+ directories during boot and to do periodic cleanup afterwards. See
+ <citerefentry><refentrytitle>systemd-tmpfiles</refentrytitle><manvolnum>5</manvolnum></citerefentry> for
+ the description of <filename>systemd-tmpfiles-setup.service</filename>,
+ <filename>systemd-tmpfiles-cleanup.service</filename>, and associated units.</para>
+
+ <para>System daemons frequently require private runtime directories below <filename>/run</filename> to
+ store communication sockets and similar. For these, is is better to use
+ <varname>RuntimeDirectory=</varname> in their unit files (see
+ <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry> for
+ details), if the flexibility provided by <filename>tmpfiles.d</filename> is not required. The advantages
+ are that the configuration required by the unit is centralized in one place, and that the lifetime of the
+ directory is tied to the lifetime of the service itself. Similarly, <varname>StateDirectory=</varname>,
+ <varname>CacheDirectory=</varname>, <varname>LogsDirectory=</varname>, and
+ <varname>ConfigurationDirectory=</varname> should be used to create directories under
+ <filename>/var/lib/</filename>, <filename>/var/cache/</filename>, <filename>/var/log/</filename>, and
+ <filename>/etc/</filename>. <filename>tmpfiles.d</filename> should be used for files whose lifetime is
+ independent of any service or requires more complicated configuration.</para>

suffix path of each other, then the prefix line is always created first, the suffix later (and if removal applies
to the line, the order is reversed: the suffix is removed first, the prefix later). Lines that take globs are

- xattr, file attribute adjustments), these are always done in the same fixed order. Otherwise, the files/directories
- are processed in the order they are listed.</para>
