Kernel Flavours
This document aims to document the flavours which exist in each release and further to document any transitions between flavours you may need to make.
What is a Kernel Flavour?
It is impossible to build a single kernel for every occasion, any such configuration cannot be optimal for all use cases. As a result we offer a number of kernel variants for each release, these variants termed flavours. We commonly refer to those flavours using the flavour name, for example: generic, generic-pae, and server.
How do we choose which Flavours are supported in a release?
At the Ubuntu Developer Summit (UDS) we will discuss the current flavours and their applicability. During this discussions we will make recommendations for additions to or removals from the supported flavours. Those recommendations feed into the development for that upcoming release.
Current Flavours
Below are the flavours as found in each release, for each there is a description of the likely use case for that flavour and where support is forthcoming; Distro (Ubuntu Kernel team) or Ports (community). Note for release which are no longer supported these are for information only.
