using LTS HWE kernels with MAAS nodes

Once you get machines setup using MAAS [1], you may want to be able to install an alternative kernel when starting a machine. Here's how to do it.

This is assuming we have already commissioned a node, but have not started it.

If we are using the _normal_ installer with MAAS do the following:
Edit /etc/maas/preseeds/preseed_master on your maas-server

Add the second line as shown:

d-i base-installer/kernel/image string linux-server
d-i base-installer/kernel/override-image string linux-generic-lts-saucy

Start the node,
Now when you boot you should be using the 3.11 series kernel.
