Hi Andreas,
 I get back on that, as I noticed that now applications linked against
gnutls in fedora wouldn't work in debian and vice-versa. While that may
not be an issue in software compiled in debian for debian, it will be
for any other software. For example I use a debian-based docker
container to test the openconnect server, and that fails to execute the
server if compiled in any other system. Closed source programs using
gnutls will have the same issue.
