<title>Control system settings with keyfiles</title>

 Separate page incorporating description from dconf.page.stub and
 paragraph from dconf-favorite-applications#all-users, but including an
 example?

To support the ability to configure the system with a text editor, 
 <sys its:translate="no">dconf</sys> has introduced
 keyfile directories. For any given system database, a corresponding
 directory can be created (with ".d" added to the filename, for example
 <file>/etc/dconf/db/local.d</file>).
 </comment>

System database files, located in
 <file its:translate="no">/etc/dconf/db</file>, cannot be edited because
 they are written in GVDB format. In order to change system settings using a
 text editor, you can modify keyfiles found in
 keyfile directories. Each keyfile directory corresponds to a
 particular system database file, and has the same name as the database file
 with a “.d” extension appended (for example,
 <file>/etc/dconf/db/local.d</file>). All keyfile directories are found in
 <file its:translate="no">/etc/dconf/db</file>, and each one contains keyfiles
 in a special format that can be compiled into the
 <sys its:translate="no">dconf</sys> database.

<listing>
 <title>A keyfile in this directory will look something like this:</title>
 <code>
# Some useful default settings for our site

[system/proxy/http]
host='172.16.0.1'
enabled=true

[org/gnome/desktop/background]
picture-uri='file:///usr/local/rupert-corp/company-wallpaper.jpeg'
 </code>
 </listing>

<note style="important">
 <cmd>dconf update</cmd> must be run whenever you modify a keyfile.
 When you do this, <sys its:translate="no">dconf</sys> compares the
 timestamp on a system database file with the timestamp on the corresponding
 keyfile directory. If the timestamp on the keyfile directory is more
 recent than the one on the database file,
 <sys its:translate="no">dconf</sys> regenerates the
 <code>system-db</code> file and sends a notification to the system
 <sys>Dbus</sys>, which in turn notifies all running applications to
 reread their settings.
