This construct would be extremely valuable to the SSSD as well: %package -n client Recommends: sssd-client.i686 if glibc.i686 > > to the foo-langpack-hu package.

It's pretty easy to install a language at package-install time, but in order to add the language subpackages for all installed packages on the system if the new langsupport package comes in will mean re-processing all of the dependencies on the installed packages.

Might be worth filing an FPC bug or two now for them to debate before pushing too hard here. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlNFZeQACgkQeiVVYja6o6Nv7ACgom5qypruoq68WLtnFqLydelm ykkAn21vSW53VnMypMNz+amO9AaTfKrl =CKpf -----END PGP SIGNATURE----- -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
