So, do you have views on:

* general policy (my suggestion is that we default to not supporting 
kernel versions not maintained upstream, unless we believe in a particular 
case that there are important distribution versions using those kernels 
that make it desirable to support using them);

* moving to requiring 2.6.32, the oldest currently-maintained kernel 
series, for glibc 2.20 (release due July 2014)?
