Michal Schmidt 7cf55dd070 man: overwrite vs. override
'overwrite' conveys the idea of the old text being destroyed.
'override' does not. It is more similar to 'overrule'.

<title>Description</title>
<para><command>systemd</command> uses
files from the above directories to configure
additional binary formats to register during boot in
the kernel.</para>

<title>Configuration Format</title>
<para>Each file contains a list of binfmt_misc kernel
binary format rules. Consult <ulink
url="http://www.kernel.org/doc/Documentation/binfmt_misc.txt">binfmt_misc.txt</ulink>
for more information on registration of additional
binary formats and how to write rules.</para>
<para>Empty lines and lines beginning with ; and # are
ignored. Note that this means you may not use ; and #
as delimiter in binary format rules.</para>
<para>Each configuration file is named in the style of
<filename>&lt;program&gt;.conf</filename>.
Files in <filename>/etc/</filename> override
files with the same name in <filename>/usr/lib/</filename>.
Files in <filename>/run</filename> override files with
the same name in <filename>/etc/</filename> and
<filename>/usr/lib/</filename>. Packages should install their
configuration files in <filename>/usr/lib/</filename>, files
in <filename>/etc/</filename> are reserved for the local
administration, which possibly decides to override the
configurations installed from packages. All files are sorted
by filename in alphabetical order, regardless in which of the
directories they reside, to ensure that a specific
configuration file takes precedence over another file with
an alphabetically later name.</para>
