And to elaborate what on what t.gummerer meant earlier: git update-index --assume-unchanged is often abused to ignore already tracked files, thinking that they can change the file while git happily ignores it. --assume-unchanged was neaver built for this purpose, it's built for large code bases where parts of the code base never changes, and git checking this part would only slow it down. So that's why it's called a promise to git that the file never changes, because git doesn't check the status of the file everytime you run git status. But because the file is still tracked, any commit that changes the file causes git to still update that file, but git will then protest, because it found it the file actually changed in the mean time, and you broke that promise. But also already said, this only applies to tracked files, so not to files that aren't being tracked in the first place.
