From: Fabiano Rosas <faro...@suse.de>
Add a smoke test that migrates to a file and gives it to the
script. It should catch the most annoying errors such as changes in
the ram flags.
After code has been merged it becomes way harder to figure out what is
causing the script to fail, the person making the change is the most
likely to know right away what the problem is.
