Kernel and Gadget Specification

[Mark Shuttleworth]

With snaps on classic Ubuntu I would think we have plenty of opportunity
to grow the community playing with snapcraft right now.

There's no rush on the pure-snap Ubuntu Core images. Let's iron out any
issues with snaps on classic and the snap publication mechanisms. We'll
all meet up in two weeks time to go deep on the pieces for Ubuntu Core.

I appreciate the desire to start right away with something that won't
break, but even the basic Ubuntu Core image needs to do things that
should happen in the gadget snap (like hostname setting). Right now, the
priority for all of us should be making sure people are not blocked on
making snaps for classic systems, because it will take a little while
for people to become familiar with snapcraft etc. We have time on Ubuntu
Core.
