There is an interesting thread happening on Reddit right now. Eduran asks "What do I need for a career in sys admin"?
"What kind of schooling do i need if i want to work in linux administration? I already have a couple years in linux experience (messing with Arch and basically just soaking things up like a sponge), and the linux world fascinates me to no end."
What advice would you give him? Definitely comment in the thread if you've got a reddit accout. I'm adding a link to this post in the conversation. Chime in! How did you get started?
