[Merge] ~seb128/livecd-rootfs:canary-image-tweaks into livecd-rootfs:ubuntu/master

[Michael Hudson-Doyle]

Review: Approve

Hi, I'm sorry I didn't see this when it was first posted. Looks fine (I should probably remove lupin-casper from the server side of things too). I wonder if in the long run we will want a different seed for the new installer live session?
