    <title>Description</title>

    <para>
      The <filename>config</filename> file in an OSTree
      repository is a "keyfile" in the <ulink
      url="http://standards.freedesktop.org/desktop-entry-spec/latest/">XDG
      Desktop Entry Specification</ulink> format.  It has
      several global flags, as well as zero or more remote
      entries which describe how to access remote
      repositories.
    </para>
    
    <para>
      See <citerefentry><refentrytitle>ostree.repo</refentrytitle><manvolnum>5</manvolnum></citerefentry> for more information
      about OSTree repositories.

	<para>
	  If you disable fsync, OSTree will no longer be robust
	  against kernel crashes or power loss.
	</para>
	<para>
	  You might choose to disable this for local development
	  repositories, under the assumption they can be recreated from
	  source.  Similarly, you could disable for a mirror where you could
	  re-pull.
	</para>
	<para>
	  For the system repository, you might choose to disable fsync
	  if you have uninterruptable power supplies and a well tested
	  kernel.
