In the UDS discussions around this, it was pointed out that we don't
recommend LTS->LTS upgrades until the first point release, which means that
for 12.04 w/ 12.10 backport, you don't get offered an LTS upgrade until a
full three months after 12.10 EOL.  So the expected upgrade path will be
12.04 w/ 12.10 backport -> 12.04 w/ 14.04 backport -> 14.04; users will have
to do the upgrade in two steps, but at least there will only be one kernel
upgrade to deal with.
