[Merge] livecd-rootfs:default-compat into livecd-rootfs:ubuntu/master

[Christian Ehrhardt ]

Review: Approve

As pre-discussed with Brian, I see no problem bumping that up to 1.1.
You mentioned Xenial up there, but it goes further -  even Trusty was already ok to read this format.

It surely is reasonable to ask the other consumers which John seems to already have started.

+1 from my POV
