how to maintain self-service agents?

[rusefillc]

• we need "hardware in the loop" continues integration - well, we have it https://github.com/rusefi/rusefi/blob/master/.github/workflows/hardware-ci.yaml
• all existing agents are across the country and not controlled by rusEFI see https://github.com/rusefi/rusefi/pull/6998
• there are five intel NUC in NJ
• there is drama with reliable WiFi re-connect by those NUCs?

Question: what's the fancy way to maintain three-file lightweigh linux nucs, to make sure those are very similar to each other and power up after reboot and do not require babysitting?

Do I have to replace wifi with Ethernet to gain stability?
