misc improvements to build, runtime and documentation

[jimdigriz]

Several proposed improvements:

• remove the need for privileged
• reduce final image by ~2.5GB (from 6GB)
• support fallback from kvm to tcg
• use shell expansions and push DISPLAY into ENV so it does not need to be supplied
• provide example on how to use PulseAudio
  • partly resolves Possibly simpler invocation #71
  • note that due to (seemingly) the lack of codec driver support there still is no audio support in the guest

This looks awesome, I will go thru it tomorrow :) thanks for working on this

I originally had the shell expansions on RAM CORES etc., only issue I could foresee was people would have to dig to see it.

Excited to build your image tomorrow 😁

It's all proposals and just the collection of notes I have myself when using Docker-OSX. Use what you can and find useful!

[sickcodes]

Definitely will!

Running in non privileged has always been a goal, I was unaware how to achieve that, thanks for submitting this

@jimdigriz Dude this PR is awesome, taught me some new stuff :)

Tested, worked like a charm.

Has a cool verbose boot now too, might be upstream tho.

Thanks again!

Really pleased you found it useful and worth reviewing and accepting.

Thank you for putting this together so lazy people (like me!) can quickly get a local macOS instance.
