<title>Lock down specific settings</title>

To lock down a <sys its:translate="no">dconf</sys> key, you will
 need to create a <file its:translate="no">locks</file> subdirectory in the
 keyfile directory. The files inside this directory contain a list of keys to
 lock. Just as with the
 keyfiles, you may add any
 number of files to this directory. Here is an example of what one might look
 like:

<steps>
 <title>Lock a setting</title>
 <item>
 Before you can lock down a key, you need to set it. This example shows
 how to lock <link xref="desktop-background">a background setting</link>
 once it has been set. At this point, you should have
 <link xref="dconf-profiles">a <sys>user</sys> profile</link> and
 <link xref="dconf-keyfiles">a keyfile</link> with the settings that you
 want to lock down.
 </item>
 <item>
 Create a directory named
 <file its:translate="no">/etc/dconf/db/local.d/locks</file>.
 </item>
 <item>
 Create a file in the
 <file its:translate="no">/etc/dconf/db/local.d/locks/</file> directory
 and list one key per line. For example, create
 <file its:translate="no">/etc/dconf/db/local.d/locks/00_default-wallpaper</file>:
<code its:translate="no">
# prevent changes to the background
/org/gnome/desktop/background/picture-uri
/org/gnome/desktop/background/picture-options
/org/gnome/desktop/background/primary-color
/org/gnome/desktop/background/secondary-color
</code>
 </item>
 <include href="dconf-snippets.xml"
 xpointer="xpointer(/*/*[@xml:id='dconf-update'])"
 xmlns="http://www.w3.org/2001/XInclude"/>
 </steps>

<note>
 As of <app its:translate="no">dconf</app> 0.7.4, lockdown is only
 supported on a per-key basis for performance reasons; you may not yet lock
 entire subpaths. There are plans to address this in future releases.
