This is exactly why I gave up a position as a full stack / devops engineer in favor of going back to low level drivers - there were too many unknowns, and far too many unknown unknowns often paired with expectations of prompt (and cheap) solutions to complicated issues.

Technically it was interesting and challenging, but in terms of stress just not worth it. You could pay me twice my current salary and I still would not go back to it. Now I try to place myself as far away from paying customers as technically possible.
