Saves a bunch of money, makes cleaning up viruses easier (just reboot/reimage/clean up data) and really lowers TCO. The real PITA is that this system requires six sigma uptime (99.9999%) and really complex networking/data center operation. However, once running it is much easier to deal with than 6,000 desktops running who knows what version of Windows... Just a though folks. Fedora is (mostly) NOT for running a real time system. RHEL/Centos is. I've been through this discussion before but I have the EAR of RedHat (I work in an office that runs, literally, 500 RHEL/RHAS servers). They are the one that said this, when Fedora was introduced. I ran RH 7.1-9.1, FC 1-4 and then moved to a Mac. Due to my work on several FOSS projects, I am back trying to install Fedora 13. This has all the appearances of being a real no-go. I will try to get CentOS 5.5 installed on it using information gained here and see where this goes. I need a stable 'table' and I'm not enamored with Ubuntu (it makes Fedora look polished by comparison.) You folks are great, but when you run bleeding edge beta software, it is going to break every once in while and picking up the pieces can and is a real bother. Rule of thumb: If you can afford to loose it, run Fedora. If you cannot and it absolutely has to be as close to 100%, run RedHat Linux.
