Hi, I think I finally understand your reasoning (also thanks to the thread on guix-devel - https://lists.gnu.org/archive/html/guix-devel/2022-08/msg00167.html) and agree. Will send in V3 shortly with license:isc added to the list of licenses with a comment. Thank you for your elaborations and patience. - pukkamustard Maxime Devos writes: > [[PGP Signed Part:Undecided]] > On 19-08-2022 15:41, pukkamustard wrote: > >> I'm no legal expert, but I think I am free to distribute it only >> under LGPL-3.0-or-later (and not also ISC).
