I think my original examples got a but = lost in the various back and forth. So, let me reproduce and re-match: 1) where no version is indicated, the license text of GPL (all = versions) tells us what to do, " If the Program does not specify a=20 version number of this License, you may choose any version ever = published by the Free Software Foundation.=E2=80=9D=20 - thus, use: SPDX-License-Identifier: GPL-1.0-or-later example: * May be copied or modified under the terms of the GNU General = Public License This is what Allison and I were going back and forth on. Net sum being: = I was pointing out that under a literal reading of the license, such a = unclear reference to just =E2=80=9CGPL=E2=80=9D would be = GPL-1.0-or-later=20 I think this is where your point is spot on and confirms my memory of = the various discussions: > I agree that one can use GPL-1.0-or-later in this case well (which was > discussed down thread), but I also agree with the argument (also = downthread) > that there is no *requirement* to include GPL-1.0 in the mix.

I checked with > Fontana too and he agrees with this as well. I think what I was looking for here, was confirmation as to whether we = want to do the =E2=80=9Cliteral=E2=80=9D GPL-1.0-or-later option that = the license provides for, or trigger the option to =E2=80=9Cchoose any = version=E2=80=9D and go with GPL-2.0-or-later for consistency of v2 = across the kernel and for other reasons I believe you raised regarding = GPL-1.0 Thoughts? thanks, Jilayne > On May 21, 2019, at 11:24 AM, Bradley M.
