Public bug reported:

[ Impact ]

As part of 24.04.2, we should have enabled the HWE kernel for desktop and 
server.
Desktop switches to HWE by default, but server images need to offer both.
Additionally, desktop flavors make that switch too at the same time.

Unfortunately, this was overlooked for .2, but will be necessary for
24.04.3. The goal is to land that as soon as Noble .2 is out, so that
people really needing the HWE stack will be able to grab a daily.


[ Test Case ]

Wait for daily builds once the HWE kernel is available.
* Double check that the images build correctly.
* Boot the desktop image and confirm it's using the HWE kernel.
* Boot the server image and confirm there's a selection of which kernel to use 
and both GA and HWE kernels work.
* Check flavor desktop images and make sure those also use the HWE kernel.


[ Where problems could occur ]

Any regressions would possibly be around kernel selection for our
images. Maybe checking flavors if they are still using the right ones
would make sense. Most issues would be visible with image build
failures.


[ Other Info ]

6.11 HWE stack has already landed in noble-updates, so it's very
straightforward to confirm which kernel is in use (vs 6.8, GA kernel)
