The result can be a license with contraditory terms, as in this case (GPL requires no additional restrictions; yet additional restrictions are required). Since the terms are contradictory, the recipient cannot simultaneously satisfy all the terms of the license; thus the recipient has no valid license in the work. -- \ "All good things are cheap; all bad are very dear." -- Henry | `\ David Thoreau | _o__) | Ben Finney -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

If it's a license derived from the GNU GPL, it cannot refer to the GPL terms, but must copy and modify them instead. And it cannot be named GPL or mention GNU. See http://www.gnu.org/licenses/gpl-faq.html#ModifyGPL It's not what has been done by Red Hat. They licensed their work under the GNU GPL v2 + additional restrictions.

In section 6 of the GNU GPL v2, it's clearly stated that no further restrictions *beyond the ones found in the GPL terms* can be imposed. But such restrictions are imposed, at the same time. > > A "GPL plus restrictions" is only invalid when the GPL is granted by > one entity, and the restrictions imposed by a different one.

A "GPL plus restrictions" is only invalid when the GPL is granted by one entity, and the restrictions imposed by a different one. I can't licence my code as "plus restrictions" and mix it with "pure GPL" code by someone else. Cheers, Wol -- Anthony W.

To the best of my knowledge, the FSF is like most of the free software community in generally discouraging the creation such derivative licenses. In any case, the copyright owner for this software really should talk to the FSF about getting permission to use the text of the GPL in a "GPL+limitations" type of license.

You may not impose any further restrictions with respect to the *rights granted by the GPL*. But there are already such restrictions, and you cannot remove them because you are not the copyright holder. Hence you cannot comply with the license and the work is undistributable.

The fact that a clause is *similar* to one seen in a GPLv3 draft has *never* been a valid reason why it should be considered DFSG-free. Please, let's avoid drifting away from the topic we are talking about: we are trying to analyze a GPLv2 + restrictions licensing scheme. -- http://frx.netsons.org/doc/nanodocs/testing_workstation_install.html Need to read a Debian testing installation walk-through? .

This makes it GPL incompatible, but I think it's still DFSG free. The GPL says: """ 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. """ So if you redistribute the Program, you may not impose any further restrictions. Obviously others, like Debian, could not add additional restrictions. However, assuming RedHat is not using parts of GPL software in their fonts, they are free to add addition restrictions the their originally licensed software--as they copyright holders, they can use any license they want. So if they say their fonts are GPL+restriction, the fonts are NOT GPL compatible, but as long as the restriction itself is DFSG free, the work as a whole should be fine. The restriction they've added itself is very GPLv3-esque, so I don't see why it wouldn't be DFSG free[1]. [1] Cue someone who will point out a billion reasons why they think similar clauses in GPLv3 drafts aren't DFSG. -- Wesley J.
