[Bug 1508565] Re: maas uses 3.13 (hwe-t) kernel which does not work on non-virtual IBM power

they could apt-get install it after the fact (same as for option 'b').

> What are consequences to support on hwe-u? Are they know forced up to
16.04 sooner (since hwe-u does not have lifetime of hwe-t)?

Well, no.  see [1], specifically the picture at [2].  An installed
system would get updates on the installed 'linux-generic-lts-<release>'
kernel until August of 2016 (the release of 14.04.5).  At that point,
they  no longer get kernel updates, but get a message that says "You
should upgrade to linux-generic-lts-xeniel'.    Also note, that your
question really should say hwe-v.  My testing showed that hwe-v would be
selected if available, and we should make it availble in the released
stream (as it is offiically released).

> Or anyone wanting to recreate specific certification needs to know
what the point in time kernel was...

Cert has this general issue.  We have no 'snapshot.ubuntu.com' (see
http://snapshot.debian.org/ for reference), so there is actually no way
to reproduce a point in time of ubuntu other than GA (because you can
jsut disable -security and -updates to get GA only).  Ie, as soon as you
hit archive, you can only get updates.
