I'd love to hear more about the ax3 w/NetInstall container solution.
Here.
No other steps of PC needed?
No, but you do still have to set up the container on a per-case basis. Each difference in:
- CPU type
- package set
- init script
etc. will require a new container.
Fight it if you like, but a Linux VM bridged to a single host-side interface and running my provided wrapper shell scripts is the easy path.
