server editions are a different animal
To start off, thanks for the cert links! LPI.org had a link to a free ebook (Linux Essentials) from linupfront that should be really helpful for the IT side of things. I'm in a Windows shop but would like to replace some of our file and web servers with Linux. I've tested Ubuntu Server 12.04 on a VM, but have had mixed results--Apache install/removal failure, failure halfway through the GUI install. Speaking of which, everyone on the forums I read said never to install the GUI on a Linux server in the first place because of the performance hit, although they also seemed to be purists. There was a fairly clear message, at least in those forums, that GUIs are for the incompetent.
Anyway, I know the errors happened because I'm a Linux noob trying to do tricky stuff, but for this to work, I'll need to be able to convince our team that a Linux server is safer, faster, and not too difficult to learn and fix. I'm convinced on points 1 and 2, but the last one is looking like a hard sell.
