Comment # 8 on bug 1091097 from Thorsten Kukuk

If we speak really about images where we use kernel-default-base, the request
is invalid. The virtualisation images are not for development and debugging,
they are for customers who need a minimal footprint and easy way to deploy.
For internal we can build images with kernel-default.
Adding all helpful modules to kernel-default-base makes it unuseable as a small
kernel for virtualisation environments, where you don't want over 600MB
installed if 67MB are enough.
