Comment 8 for bug 1273382

as Mike points out, it actually makes a lot of sense to also have MAAS just default to the latest HWE kernel for enlistment and commissioning.

MAAS should be, IMO, smart enough to see that Trusty has a HWE-U kernel and boot media and start using that for enlistment and commissioning to ensure that newly discovered systems are enlisted and commissioned properly (all their hardware is addressed by the right drivers and probed successfully).

Setting a default kernel as noted in previous comments is also a helpful thing to have, but really, MAAS should be defaulting to whatever is the most recent kernel it has for a given release.p
