+    <title>Description</title>
+
+    <para>The <filename>/etc/os-release</filename> and
+    <filename>/usr/lib/os-release</filename> files contain operating
+    system identification data.</para>
+
+    <para>The basic file format of <filename>os-release</filename> is
+    a newline-separated list of environment-like shell-compatible
+    variable assignments. It is possible to source the configuration
+    from shell scripts, however, beyond mere variable assignments, no
+    shell features are supported (this means variable expansion is
+    explicitly not supported), allowing applications to read the file
+    without implementing a shell compatible execution engine. Variable
+    assignment values must be enclosed in double or single quotes if
+    they include spaces, semicolons or other special characters
+    outside of A–Z, a–z, 0–9. Shell special characters ("$", quotes,
+    backslash, backtick) must be escaped with backslashes, following
+    shell style. All strings should be in UTF-8 format, and
+    non-printable characters should not be used. It is not supported
+    to concatenate multiple individually quoted strings. Lines
+    beginning with "#" shall be ignored as comments.</para>
+
+    <para>The file <filename>/etc/os-release</filename> takes
+    precedence over <filename>/usr/lib/os-release</filename>.
+    Applications should check for the former, and exclusively use its
+    data if it exists, and only fall back to
+    <filename>/usr/lib/os-release</filename> if it is missing.
+    Applications should not read data from both files at the same
+    time. <filename>/usr/lib/os-release</filename> is the recommended
+    place to store OS release information as part of vendor trees.
+    <filename>/etc/os-release</filename> should be a relative symlink
+    to <filename>/usr/lib/os-release</filename>, to provide
+    compatibility with applications only looking at
+    <filename>/etc</filename>. A relative symlink instead of an
+    absolute symlink is necessary to avoid breaking the link in a
+    chroot or initrd environment such as dracut.</para>
+
+    <para><filename>os-release</filename> contains data that is
+    defined by the operating system vendor and should generally not be
+    changed by the administrator.</para>
+
+    <para>As this file only encodes names and identifiers it should
+    not be localized.</para>
+
+    <para>The <filename>/etc/os-release</filename> and
+    <filename>/usr/lib/os-release</filename> files might be symlinks
+    to other files, but it is important that the file is available
+    from earliest boot on, and hence must be located on the root file
+    system.</para>

+        version, excluding any OS name information, possibly including

+        characters outside of 0–9, a–z, ".", "_" and "-") identifying
+        the operating system, excluding any version information and
+        suitable for processing by scripts or usage in generated
+        filenames. If not set, defaults to

+
+        <listitem><para>A space-separated list of operating system
+        identifiers in the same syntax as the <varname>ID=</varname>
+        setting. It should list identifiers of operating systems that
+        are closely related to the local operating system in regards
+        to packaging and programming interfaces, for example listing
+        one or more OS identifiers the local OS is a derivative from.
+        An OS should generally only list other OS identifiers it
+        itself is a derivative of, and not any OSes that are derived
+        from it, though symmetric relationships are possible. Build
+        scripts and similar should check this variable if they need to
+        identify the local operating system and the value of
+        <varname>ID=</varname> is not recognized. Operating systems
+        should be listed in order of how closely the local operating
+        system relates to the listed ones, starting with the closest.
+        This field is optional. Example: for an operating system with
+        <literal>ID=blag</literal>, an assignment of
+        <literal>ID_LIKE="rhel fedora"</literal> would be appropriate.
+        For an operating system with <literal>ID=gnewsense</literal>, an
+        assignment of <literal>ID_LIKE=debian</literal> is

+
+    <para>Note that operating system vendors may choose not to provide

+
+    <para>Operating system vendors may extend the file
