First time trying the installer. It appears to have worked. But I have quesitons that I suspect have been discussed at length in other reviews...

1. [ERROR]: FlowFuse one time code is required for installation - so you can't just install the agent?
2. No choice about setting up a service - not what I was expecting
3. No choice on user dir - so I can't run multiple agents locally (edge case, and I know there is an issue open for this)
4. Not sure what to do after the install completes... needs a clear 'what to do next' message like You can access the agent through the FlowFuse platform at <url> or something like that.

✔ Success
Configuration completed successfully!
Configuring FlowFuse Device Agent to run as system service...
Installing service flowfuse-device-agent for darwin
FlowFuse Device Agent installation completed successfully!
The service is now running and will start automatically on system boot.

No idea how to clean this up or check the logs or anything else I'm used to doing when running the agent manually.

The goal on the first iteration is to simplify the device agent onboarding process. Installation of the device agent without OTC will be handled in later iteration (tracking issue).
Regarding setting up a service - what kind of choice would you have?

3. No choice on user dir - so I can't run multiple agents locally (edge case, and I know there is an issue open for this)

Indeed, this feature will be implemented in the next version.

4. Not sure what to do after the install completes... needs a clear 'what to do next' message like You can access the agent through the FlowFuse platform at <url> or something like that.

Improved summary message here.

@knolleary can I get one more look, please?

My suggestion was to include a link back to the platform - as we have the url available to us via the -u flag - rather than the docs. Is that possible?
