Description Stevan White 2025-02-11 14:13:21 UTC

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.
