Here is a proof-of-concept: http://review.coreboot.org/#/c/5191 . > This requires user to do right manipulations. While keyboard and chair are usually fine, the space between them exhibits strong bug-inducing properties. The idea of the script is to reduce a possibility of user error creating strange reports. In this case the common erro I expect is using a stale file fom some other version. It's a particularly nasty one as at first glance in may look fine but would be almost useless to track how details changed from one submit to the next. If we let user supply files at all, it should be added to report, not replace files, and it should have some prefix to clearly indicate that user was involved in creating them.
