## Current Behavior
The daemon is hard-disabled in docker, even if you try to explicilty
enable it using the `NX_DAEMON` env var.

## Expected Behavior
We should disable the daemon by default in docker but allow users to
opt-in using the env var. There might be issues that come with that but
since it's opt-in, it will be at their own risk.
