I would like to see a howto feature a perfect server setup of fedora and debian, but without management tools like ISPConfig, Webmin, CPanel, etc. A guide that covers hints and tips how to set up virtual hosts, DNS records, email, log file rotation and all the stuff by hand that are usually set up by control panel software.
I'm sure many people would be interested to see how one would efficiently set up a server without aid of control panel software. Especially those who want minimal setups by installing and setting up only what they really need.
