GLEP58: under "Procedure for verifying an item in the MetaManifest" 4.2: "M2-verifying the contents of the Manifest."
Where "M2-verify" is the verb describing the verification of a Manifest. It _may_ include signature validation. > So what's the advantage of individually signed Manifests? Basically making sure that your SSH keys weren't stolen. They explicitly protect the commit from the developer to infrastructure. MetaManifest protects the integrity of the contents from infrastructure out to the user. It does NOT validate the functionality of the tree or any prior injection. > The only thing we can check: Is the key used for signing listed in ldap > (and thus in "the keyring of automated Gentoo keys")?
