Instead of running losetup and then using phy:loop0, you can now just specify 
file:/path/to/file

We've got rid of the xda devices - use the sd* and hd* devices instead, then 
it should work.

Did you see xda in the documentation somewhere?  It'd be nice to know where 
it's still mentioned so that we can delete it!

Cheers,
Mark
