Quite frankly, I don't know | why people run Fedora servers -- if it's Red Hat compatibility you want, | there's CentOS. | Linux kernels seem to be pretty good these days. I ran Red Hat Linux 7.3 24/7 for over 6 months, and it was discontinued years ago. I recognize that this is by no means a record. It did not crash after 6 months, but I upgraded that box to CentOS 4 and it has been running that a long time. That box has minor hardware problems that do not happen often enough to find the real cause. But it stays up months at a time. All that box does is run BOINC and a printer server (CUPS). This machine does not crash, but it gets rebooted whenever a new kernel comes out, and has been up almost a month. It run RHEL5. I would think Fedora's kernel would probably be OK, but the other bleeding edge stuff I would not risk a serious server on. - -- ~ .~.
