   If you can't sign off on it, then Junio shouldn't take it, since
   you're basically saying that you cannot say that you own the
   copyrights or cannot license it under the appropriate copyright.

That is not what I am saying. In either case, I already explained why I cannot agree to the DCO above. And you are right, Junio shouldn't apply the patch if it goes against commit policies.

   Yes, it speaks of "open source licenses", but it says: "under the
   open source license indicated in the file", and "appropriate open
   source license".

That is a good point, almost none of the files in git specify the license so it is impossible to know what one is actually agreeing too.

I would suggest the following update to the DCO, it makes it more general both to free software hackers, and open source hackers alike.
