VOLUME_IDENTIFIER_KIND_CLASS

The string used to obtain the volume class with g_volume_get_identifier().

Known volume classes include device, network, and loop. Other classes may be added in the future.

This is intended to be used by applications to classify #GVolume instances into different sections - for example a file manager or file chooser can use this information to show network volumes under a "Network" heading and device volumes under a "Devices" heading.
