          all represent <a class="ulink" href="http://en.wikipedia.org/wiki/Block_device#Block_devices" target="_top">block devices</a>.

          Such objects implement the

          D-Bus interface and may optionally implement other D-Bus interfaces such as

          Note that interfaces may be added and removed at
 
38
          run-time. For example, if a block device is full of zeroes
 
39
          (or, at least, have zeroes in the known metadata areas), it
 
40
          will not intially implement the <a class="link" href="gdbus-org.freedesktop.UDisks2.Filesystem.html#gdbus-interface-org-freedesktop-UDisks2-Filesystem.top_of_page">org.freedesktop.UDisks2.Filesystem</a>

          interface; however, if a filesystem is later created on the device
 
42
          (using, say, the
 
43
          <span class="citerefentry"><span class="refentrytitle">mkfs</span>(8)</span>
 
44
          command) and the filesystem is recognized by the OS (specifically, recognized by
 
45
          <span class="citerefentry"><span class="refentrytitle">udev</span>(7)</span> and its device probers), the object will gain the interface. If the device is later zeroed or formatted for use as e.g. swap-space, it will lose the
