--- Comment #5 from Ove Kaaven ovek@arcticnet.no 2007-12-29 20:55:04 --- As for the Liberation fonts, it may seem strange, but if you're curious, it's basically like this: The license of the Liberation fonts is standard GPLv2 plus an extra restriction or two. The text of the GPL says that you can't add non-GPL restrictions of your own, they'd violate the GPL. The FSF does permit modified licenses based on GPL, but *only* if they change the name of the license to something other than GPL, which Red Hat hasn't done. Thus, the whole Liberation font license is invalid, and Debian has no legal right to redistribute. But Red Hat does not acknowledge the problem, nor does anyone else, hence it doesn't get fixed.
Messy...
