The environment variables don't appear to be respected, and it seems like there's a daemon install missing? I tried also using the raspberry pi deb directly but that was just getting weird.

TOKEN environment variable not found.  We'll prompt for a token.
COMPUTERID environment variable not found.  We'll create a new computer in the account.
COMMANDS environment variable not found.  We'll use the default commands.
Run installdaemon.sh to install the triggercmdagent daemon so it runs during boot
Daemon install: false
No token exists.  Login to request one.
