Description Volker 2014-06-13 15:18:30 UTC 
Steps done:
1. I did a build which ran fine.
2. I changed the license file of our own recipes, not in the recipe but the license file itself
2.1 I did not fix the md5sum in the recipes
3. I executed the image build again in the hope to find easily the packages that needs the license md5sum fixed
4. the build did not run:
---
NOTE: Tasks Summary: Attempted 2558 tasks of which 2558 didn't need to be rerun and all succeeded.
---

I would have expected that all packages that use this changed license file would have been rebuild. Rebuilding everything from scratch takes much longer.

It is unclear if this is a bug or feature. Feature in a way that "code has not changed, packages don't need to be rebuild".

For clarification, from our discussion on IRC this is a file referred to in LIC_FILES_CHKSUM.

This should be fixed as of:

The name of the test is lic-checksum.LicenseTests.test_foo. I'm going to send a patch to change the name very soon since test_foo was not intentional.
