Bug Description

Building the snap with confinement: devmode is a pain because it makes the ubuntu-image snap much less discoverable (by design of snapd). Why do we need devmode anyway? We ship our own mkfs.ext4 so we shouldn't need sudo in the snap.

Let's try to get rid of it.

when setting up the snap build on launchpad you can use the ubuntu-image PPA as default archive and put the e2fslibs (that cause this requirement) into stage-packages, that way devmode should be avoidable since the snap will ship its own version of e2fslibs so no sudo will be needed.

That does not cause this requirement, the snap as it exists today is already
bundling the correct version of e2fsprogs.

The root reason we have to use devmode is filesystem access. By definition, ubuntu-image is a tool that you use to manipulate files provided to it from outside its snap context. This ties in with some future work that I know has been planned for snapd, but I don't think there's anything that can realistically be done to remove devmode for the 0.11 release.

At a minimum, we'll need 'home' interface since my experimental branch failed without it. I am going to de-milestone this from 0.11.

As @vorlon points out, once u-i is a classic snap, we can get rid of the ugly /tmp handling code.
