Is it possible to make money using your Linux knowledge if you're not a developer? I know I can become a professional devops or sysadmin if I take some courses and master advanced networking. But is there something I can do now as an average, moderately experienced linux user?
I think the internet can inflate this view. In my experience supporting devs, there are many very smart people in their wheelhouse who are not very good at system administration. I think it is much like academics who are also often assumed to be good at computers, rather than good at what they do on computers.
