Hi Milosz,
This helped greatly, thank you! Turns out my main issue was that I had tab spacings in my definition, and I didn't find out until checking the status of ser2net with systemd.
But another problem has come up, regarding actually running tests (I was just doing the boot action until now). I need both the deploy and test action to run tests, which leads to the following section: For my question about the test definition, I forgot to mention in the original, but the file system is read-only, and I don't want to have any overlays from deploy (a requirement I'm pretty sure), from my research into deploy (looking at the deploy action reference https://validation.linaro.org/static/docs/v2/actions-deploy.html), and I can't seem to find anything to work.
Is there anything I'm perhaps missing? Or will I need to try get a custom deploy method?
Best regards, Michael
