lxd fails in beta15 when installing via snap

[Matthew Helmke]

I did a successful test install using the juju/devel PPA. Then, I tried a fresh install in a fresh VM to test the snap package.

This is a snap specific issue I think and not directly tied to a juju release. Targeting at 2.1 since we should not block the release of Juju 2.0 on this, but I want to make sure we track it. Ideally we should look into starting a project for just the snap and associating this bug with that work there to work out what we need to do to have Juju and LXD play nice together in a snap world on the same system.

[Nicholas Skaggs (nskaggs)]

This is actually a problem with snap-confine, not the juju snap specifically. See the duped bug.
