Tracker does periodic cleanups of data on removable volumes that haven't
been seen since 'removable-days-threshold', and will also remove all data
from removable volumes if 'index-removable-devices' is disabled.
FIXME: not yet possible to test this - we need some way of mounting
a fake removable volume:
#dconf = DConfClient ()
#dconf.write (cfg.DCONF_MINER_SCHEMA, 'index-removable-devices', 'true')
#self.mount_test_removable_volume ()
#self.add_test_resource ("urn:test:1", test_volume_urn)
#self.add_test_resource ("urn:test:2", None)
# Trigger removal of all resources from removable devices
#dconf.write (cfg.DCONF_MINER_SCHEMA, 'index-removable-devices', 'false')
# Check that only the data on the removable volume was deleted
#self.await_updates (2)
