+Subject: [PATCH] vt/conmakehash: improve reproducibility
+
+The file generated by conmakehash capture the application
+path used to generate the file. While that can be informative,
+it varies based on where the kernel was built, as the full
+path is captured.
+
+We tweak the application to use a second input as the "capture
+name", and then modify the Makefile to pass the basename of
+the source, making it reproducible.
+
+This could be improved by using some sort of path mapping,
+or the application manipualing argv[1] itself, but for now
+this solves the reprodicibility issue.
