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

systemd-timesyncd will contact all configured system or

responds. When the empty string is assigned, the list of

NTP servers is reset, and all assignments prior to this one

Any per-interface NTP servers obtained from

take precedence over this setting, as do any servers set via

if no other NTP server information is known. When the empty

and all assignments prior to this one will have no effect.

If this option is not given, a compiled-in list of NTP servers
