The "include" files had type "book" for some raeason. I don't think this is meaningful. Let's just use the same everywhere. $ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n "http^gms' man/*.xml

systemd-timesyncd will contact all configured system or

per-interface servers in turn until one is found that

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

<varname>NTP=</varname> above. This setting is hence only used

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

string is assigned, the list of NTP servers is reset,

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

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