From 97679d18955dadaa34f9450564e44da99984d140 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Wed, 30 Sep 2015 14:55:56 +0100 Subject: siggen: Make it clear why nostamp tasks signatures don't match If you run bitbake-diffsigs against two differing sigdata files from nostamp tasks it shows no difference despite the differing checksum. Change the code so this shows up as a nostamp 'taint' and at least makes the issue clearer to the end user.
