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

<title>Description</title>
|
|
|
|
<para><filename>systemd-sysctl.service</filename> is an early boot
|
|
service that configures
|
|
<citerefentry project='man-pages'><refentrytitle>sysctl</refentrytitle><manvolnum>8</manvolnum></citerefentry>
|
|
kernel parameters by invoking <command>/usr/lib/systemd/systemd-sysctl</command>.</para>
|
|
|
|
<para>When invoked with no arguments, <command>/usr/lib/systemd/systemd-sysctl</command> applies
|
|
all directives from configuration files listed in
|
|
<citerefentry><refentrytitle>sysctl.d</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
|
|
If one or more filenames are passed on the command line, only the directives in these files are
|
|
applied.</para>
|
|
|
|
<para>In addition, <option>--prefix=</option> option may be used to limit which sysctl
|
|
settings are applied.</para>

|
|
|
<para>See
|
|
<citerefentry><refentrytitle>sysctl.d</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|
|
for information about the configuration of sysctl settings. After sysctl configuration is
|
|
changed on disk, it must be written to the files in <filename>/proc/sys</filename> before it
|
|
takes effect. It is possible to update specific settings, or simply to reload all configuration,
|
|
see Examples below.</para>
