The Linux kernel, IIRC, was made GPL2 only when GPL3 was released.
That may be, I don't know. If that was the case, then any version up to that point could be used with any GPL version, be it 3, 4, 5 ...
AFAIK Linux has been GPLv2 only since version 2.4.0, i.e. from January 4th 2001. Work on GPLv3 didn't start until late 2005. Personally I think it's only prudent to know *exactly* what license SW I write is released under. So releasing under GPLv3 only before GPLv4 is released makes sense; I also think that applying licenses retroactively is troublesome, so it's worth being specific from the beginning. OTOH it doesn't bother me at all that Arch's packaging system currently lacks a way of accurately specifying the license for some software. I think it's very little chance of that ever counting for anything in court. As long as upstream provide clear information the Arch package can say pretty much anything. /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus＠therning．org http://therning.org/magnus identi.ca|twitter: magthe
