Just enough OS for OP
#1
Hi everyone,

I have been an OP user for years, I've used the pre-configured images and I've started from scratch from other Linux distros.
After using LibreElec (Just enough OS for Kodi) I have been thinking. LibreElec boots insanely fast, because it has been stripped to the bone I guess, just enough to make Kodi work.

I realize there are major differences, but it didn't leave my mind after seeing the boot time.
I also realize that, it might not be possible to try this on an OP distribution or it might take a huge amount of time to try. 
It might be that OP really needs all the boot time, because of various Python scripts, services, starting a GUI, various webapps, etc.

But, nevertheless, might such a project "Just enough OS for OP" be interesting?
Has somebody every tried it? Any other thoughts?

Tinypilot might be an example of just enough operating system for an autopilot, never tried it but I suppose this is exactly what Sean tried to accomplish.
But, looking at OP after the GUI is loaded the startup script starts checking and starting all the services that where enabled within all the separate python applications, such as serial, i2c, etc. So in this case I think OP really would need the GUI? Unless the functionalities could be built in a CLI kind of GUI that can be run from a terminal with SSH? I know that SignalK probably doesn't need a GUI because this is just a webserver. However, the combination of OP and SignalK makes it really powerful in my opinion.

Hope there are some people who could join me in the discussion.

Not a bad idea. We could do like Ubuntu:

The current OpenPlotter images should be "OpenPlotter Desktop" and we could have a parallel "OpenPlotter Server" without GUI.

OpenCPN and some other graphical apps should not be present in "OpenPlotter Server". Its main goal should be feeding other devices running OpenCPN or run AvNav with data for navigation. Signal K could be managed remotely and we should develop a web interface to manage some openplotter settings.

Yes, maybe a really good idea.
We already had some intial discussions on web based interfaces...
I guess it would be good to collect ideas what should be included - to get a view what should be implemented first and how much effort this would be.
As an alternative OpenPlotter could continue to focus on the current approach - and there could be other images focussing on the headless approach.
From my pov it heavily depends on what others would like to see included.

We could also coordinate the efforts in OpenPlotter, OpenCPN, PyPilot, AvNav and Signal K a little, so that they work together optimally and we get the most out of the dev effort available.

Would really appreciate that.

That would be great for using a Pi Zero, I've a zero just running sigK & influx as the data hub on full time as it just sips power ?

I propose to add o-charts to that team
