     # Note that the VERSION file is something that is present in release tarballs
     # but not in git tags (at least not as of writing in v3.10.1).
     # That's why we have to create it.
     # Without this, gluster (at least 3.10.1) will fail very late and cryptically,
     # for example when setting up geo-replication, with a message like
     #   Staging of operation 'Volume Geo-replication Create' failed on localhost : Unable to fetch master volume details. Please check the master cluster and master volume.
     # What happens here is that the gverify.sh script tries to compare the versions,
     # but fails when the version is empty.
     # See upstream GlusterFS bug https://bugzilla.redhat.com/show_bug.cgi?id=1452705
