A top-level .noannex file will prevent git-annex init from being used in a repository. This is useful for repositories that have a policy reason not to use git-annex. The content of the file will be displayed to the user who tries to run git-annex init. This also affects git annex reinit and initialization via the webapp. It does not affect automatic inits, when there's a sibling git-annex branch already. This commit was supported by the NSF-funded DataLad project.
