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. That case is not a invalid license, it's a copyright violation, which is a different beast! -- http://frx.netsons.org/doc/nanodocs/testing_workstation_install.html Need to read a Debian testing installation walk-through? .....................................................
