I _think_ that that depends on whether Gentoo's license tag is meant to be the "effective" license they are distributing their Git package or attempting to encompass the license of all of the code which goes into the Git package. Fedora's Git package has: BSD-3-Clause AND GPL-2.0-only AND GPL-2.0-or-later AND LGPL-2.1-or-later AND MIT I think I was the last to touch that, in ef75bcd (update license data and convert to SPDX format, 2022-11-07). I attempted to capture all of the licensing, but I most certainly could have missed some things. And things may have changed since then too. Fedora's guidelines have a lengthy page on the License tag². It includes a 'No "effective license" analysis' section discussing this. I don't know if any of that helps. :) ¹ https://src.fedoraproject.org/rpms/git/c/ef75bcd ² https://docs.fedoraproject.org/en-US/legal/license-field/ -- Todd
