The patch changes the order of the steps to search for

"If the fixed appliance is found, libguestfs skips supermin entirely

fixed appliance."
Does anyone rely on the path-like behaviour of LIBGUESTFS_PATH? It
was a mistake to allow that originally, but we're stuck with it now
unfortunately.

The steps actually refer to the documentation. See in the same
