==========
 Defaults
==========

The Defaults plugin can be used to populate default attributes for
entries.  Defaults is *not* a Generator plugin, so it does not
actually bind an entry; Defaults are applied after an entry has been
bound, and only populate attributes that are not yet set.

Like :ref:`server-plugins-generators-rules`, Defaults supports regular
expressions in the name attribute.

For instance, to make all Service entries use the ``systemd`` tool
on Fedora 15 and the ``chkconfig`` tool on Fedora 14, you could do::

    <Defaults priority="0">
      <Group name="fedora-15">
        <Service name=".*" type="systemd"/>
      </Group>
      <Group name="fedora-14">
        <Service name=".*" type="chkconfig"/>
      </Group>
    </Defaults>

If you were to specify a ``type`` attribute for a Service entry in
Rules (or a ``type`` attribute for a BoundService entry in Bundler),
that would take precendence over the default.
