SUMMARY Burn failed due to file changing during write. STEPS TO REPRODUCE 1. Tried to back up my home directory. 2. Started burning, but continued using system. 3. OBSERVED RESULT It just failed ... EXPECTED RESULT Suggestion: The app might discover that a home directory is in the project, and warn the user that if any file is changed, a failure might occur. The app might detect this kind of problem and offer the user a choice.
