We are aware that even on a decently sized Pi, such as the Pi3, building a new kernel which for example on my 20 year old P3 Intel machine takes just about an hour, on the Pi last I had heard its something on the order of all day. And that's on it mind. I've no idea how long it takes to cross compile a kernel via either a VM of whatever release name matches the date you selected for your match. I'm not sure what I am going to do, I had originally some idea to setup an AWS instance of Debian (which presupposes that it exists) and do the whole thing in there. Suggests please folks? ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."
