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 worked in a small team and our stuff rarely broke. We set it all up to use minimal resources and mostly automated maintenance and we went unnoticed for most of my time there. Everyone else thought we were just sitting around doing nothing and getting paid for it. It created an uncomfortable environment, was glad to leave at the end of it.
