Comment:
A quick test suggests that adding a `replaces` directive is not sufficient to identify the upgrade path from `pam-gnupg-git` to `pam-gnupg`. With the new `pam-gnupg` package (with a `replaces` directive) available in a local repository, `xbps-install pam-gnupg` will properly cause removal of an installed `pam-gnupg-git-20191206_1`. However, `xbps-install -u` from the local repo will *not* attempt to replace the installed `pam-gnupg-git-20191206_1` with the new `pam-gnupg` whether or not the `replaces` directive is included.

By contrast, having an updated `pam-gnupg-git` metapackage in the local repo causes `xbps-install -u` to properly replace the existing installation, pulling in the new `pam-gnupg` by dependence.
