Well, but Greg doesn't want to declare a kernel LTS before it is released exactly so that people don't cram in lots of imature stuff which needs to be fixed up later. And I agree with him that this is going to happen if he would declare LTS kernels in advance. So I don't think this is a good alternative. Honza -- Jan Kara SUSE Labs, CR
