[Bug 1325281] Re: Cannot handle more than one kernel for generic (3.13.0-24-generic 3.13.0-27-generic)!

[Colin Watson]

This is happening because linux-signed-generic is in the live task,
which I should have realised was invalid: that expands to ABI-versioned
kernel packages, and tasks can't be updated post-release.

I've fixed this in utopic (for future stable releases) by making livecd-
rootfs 2.218 install linux-signed-generic explicitly, and removing it
from the seeds.  However, we'll need a slightly different fix for trusty
since we can't change the existing tasks: livecd-rootfs will need to
filter out kernel packages from the live seed, as well as installing
linux-signed-generic explicitly as in utopic.
