While this seem like a useful feature, it can only be implemented once
it is decided which package should take resposibility for it.  In which
package is this handled byArch, OpenSuSe 13.1, Fedora 20, ALT Linux p7,
Sabayon and Mageia 4?  Can you check, as you haveaccess to these
already?  I do not.  Knowing this might give an idea where to fix it in
Debian and Ubuntu. :)

I do not expect to have time to work on this myself any time soon, but
hope someone will. :)

Happy hacking
