[Merge] lp:~rcj/livecd-rootfs/livecd-rootfs into lp:livecd-rootfs

[Philip Roche]

Review: Needs Information

All looks sane with one question.

The use of snap_channel. Does it assume that each snap listed to install will need to be in the stable/ubuntu-18.04 (for bionic) channel or are we relying on the behaviour of the snap install to fallback to stable if the branch does not exist [1]?

[1] "Users following a branch will be automatically moved to the risk level the branch is attached to. For example, if you tell users to install your snap with the following command snap install my-app --channel=beta/fix-for-bug123, after 30 days, the branch will close and these users will be moved to the beta channel, as if they had used snap install my-app --channel=beta.
