Docbook styles required those to be present, even though the templates that we use did not show those names anywhere. But something changed semi-recently (I would suspect docbook templates, but there was only a minor version bump in recent years, and the changelog does not suggest anything related), and builds now work without those entries. Let's drop this dead weight. Tested with F26-F29, debian unstable. $ perl -i -0pe 's/\s*<authorgroup>.*<.authorgroup>//gms' man/*xml

<title>Description</title>
|
|
|
|
<para><command>nss-mymachines</command> is a plug-in module for the GNU Name Service Switch (NSS) functionality of
|
|
the GNU C Library (<command>glibc</command>), providing hostname resolution for the names of containers running
|
|
locally that are registered with
|
|
<citerefentry><refentrytitle>systemd-machined.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>. The
|
|
container names are resolved to the IP addresses of the specific container, ordered by their scope. This
|
|
functionality only applies to containers using network namespacing.</para>
|
|
|
|
<para>The module also resolves user and group IDs used by containers to user and group names indicating the
|
|
container name, and back. This functionality only applies to containers using user namespacing.</para>
|
|
|
|
<para>To activate the NSS module, add <literal>mymachines</literal> to the lines starting with
|
|
<literal>hosts:</literal>, <literal>passwd:</literal> and <literal>group:</literal> in
|
|
<filename>/etc/nsswitch.conf</filename>.</para>
|
|
|
|
<para>It is recommended to place <literal>mymachines</literal> after the <literal>files</literal> or
|
|
<literal>compat</literal> entry of the <filename>/etc/nsswitch.conf</filename> lines to make sure that its mappings
|
|
are preferred over other resolvers such as DNS, but so that <filename>/etc/hosts</filename>,
|
|
<filename>/etc/passwd</filename> and <filename>/etc/group</filename> based mappings take precedence.</para>
