+Subject: [PATCH] loader: add check for unknown file type
+
+So we can provide a meaningful error message in case the provided path
+is not accessible to running process.
+
+e.g: running HOME=/root osinfo-query os we would get
+  `Error loading OS data: Unexpected file type`
+and now we get
+  `Error loading OS data: Can't read path /root/.config/osinfo`
+
+This error was first hit with v2v [0] that was leaking $USER and $HOME
+of root user when osinfo-query as vsdm user with `sudo -c vdsm`. The
+example above is a simple way to show lack of permision of
+osinfo-query to read the root's $HOME.
