I fall under the same definition as you...Full stack developer to me means that you can find your way around installing, configuring, maintaining and debugging things throughout the entire stack, not necessarily that you can develop/program things at each level of the stack. I have built servers, installed, config'd and maintained web servers (LAMP), setup mail servers, setup networks, built web applications (front-end and back-end), debugged operating system issues, network issues, database issues, recovered lost data...and I would consider myself to be a full stack developer, but according to other peoples definitions I wouldn't be if I hadn't done any major modifications throughout each level of the stack...which by that narrow definition would mean that there are probably very few "full stack developers" in the world
