Zbigniew Jędrzejewski-Szmek fdbbee37d5 man: drop unused <authorgroup> tags from man sources
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.

<title>Description</title>
<para><filename>systemd-volatile-root.service</filename> is a service that replaces the root directory with a
volatile memory file system (<literal>tmpfs</literal>), mounting the original (non-volatile)
<filename>/usr</filename> inside it read-only. This way, vendor data from <filename>/usr</filename> is available as
usual, but all configuration data in <filename>/etc</filename>, all state data in <filename>/var</filename> and all
other resources stored directly under the root directory are reset on boot and lost at shutdown, enabling fully
stateless systems.</para>
<para>This service is only enabled if full volatile mode is selected, for example by specifying
<literal>systemd.volatile=yes</literal> on the kernel command line. This service runs only in the initial RAM disk
("initrd"), before the system transitions to the host's root directory. Note that this service is not used if
<literal>systemd.volatile=state</literal> is used, as in that mode the root directory is non-volatile.</para>
