Are we concerned about this breaking folks? Setting --root is now doing something very different than it did before.

I honestly don't know. This stuff is really broken :(

I think we're good to go. It essentially overrode the graph root before as well (that's how it was being used).

@mheon do you recall why we're not passing all env variables to conmon? I feel like we should do this since there is a growing number of those which I do not see being passed down.

I think it dates back to before we forked off Conmon, so this is probably older than my involvement in the project. I don't see a good reason not to forward on full environment?

Thanks! I will open a follow-up PR 👍
