git annex dead [repository ...] [--key key]
This command exists to deal with situations where data has been lost, and you know it has, and you want to stop being reminded of that fact.
When a repository is specified, indicates that the repository has been irretrievably lost, so it will not be listed in eg, git annex info. Repositories can be specified using their remote name, their description, or their UUID. (To undo, use git-annex semitrust.)
When a key is specified, indicates that the content of that key has been irretrievably lost. This prevents commands like git annex fsck --all from complaining about it; --all will not operate on the key anymore. (To undo, add the key's content back to the repository, by using eg, git-annex reinject.)
