I am not a git expert, but: Can't you define a pre-commit hook which either computes sha1sum of a file, and commits the file under this name instead of the name given by the user, then adds a line to your index file in a post-commit hook? Can't possible conflicts be resolved automatically if you keep that index file sorted? But that would possibly require to rewrite attack descriptions in a similar way, so that they use the checksum instead of the user-supplied file name. And when you checkout the files, they could be renamed to the user-specified file name again. Am I mising something? Can this work? Does it make sense at all? How hard would it be to implement it in a way that works flawlessly? Frank
