I agree as well. A common kernel is paramount.
OK, good. To be fair, I didn't think there would be many requirements
from the Server WG. Most of the packaging changes will likely be
driven by the Cloud WG. At the moment, it shouldn't be difficult for
Server to install both the small base kernel package and the larger
kernel-drivers subpackage (for example).
At the same time, it would be good to look over what the current
kernel is providing and see if you notice any glaring omissions in
either drivers or settings. Or at the very least, perhaps define what
kind of machines you will be targeting with the Server WG spin.
Massive 4096 multi-cored CPU machines with terabytes of DRAM and
petabytes of storage, or more commodity style hardware used in
heterogeneous environments, etc. Hopefully the impacts to the kernel
there will be minimal, but it would help us understand what you're
shooting for so we can keep it in mind.
