I’ve globally configured git master branch to use the –no-ff option in my .gitconfig file: [branch "master"] mergeoptions = “-–no-ff” When I merge a branch into master that would normally be a fast forward merge, the merge happens fine and follows the option –no-ff, creating a new commit, however my commit-msg hook does not run. (The commit-msg hook works fine in all other commits / merges.) I tried changing my commit-msg hook to just be “exit 1” and it doesn’t abort a no-ff merge, so I’m certain the hook is just not being executed.
