<p>For <sys its:translate="no">dconf</sys> to work correctly when using
<sys>Network File System</sys> (<sys>NFS</sys>) home directories, the
<sys its:translate="no">dconf</sys> <em>keyfile back end</em> must be
used.</p>
<steps>
<item>
<p>Create or edit the <file its:translate="no">/etc/dconf/profile/user</file> file
on every client.</p>
</item>
<item>
<p>At the very beginning of this file, add the following line:</p>
<code><input its:translate="no">service-db:keyfile/user</input></code>
</item>
</steps>

<p>In-process changes will take effect immediately, but out-of-process
changes will be delayed by the poll time on GFileMonitor.</p>
</comment>
<p>The <sys its:translate="no">dconf</sys> <em>keyfile back end</em> will only
take effect the next time that the user logs in. It polls the keyfile to
determine whether updates have been made, so settings may not be updated
immediately.</p>

<p>According to Ryan, "SIGBUS being semi-randomly delivered to your
processes is a real downer". This means stuff will crash.</p>
</comment>
<p>If a <em>keyfile back end</em> is not used, the user settings may not be
retrieved or updated correctly.</p>
