Marcel Wegerman got interviewed by the german Linux Magazin on agile sysadmins. It's titled (german) "Agile Methoden auch in der Systemadministration".
It's really nice to someone promoting the same ideas.
Last year Marcel did a Lightning talk at the 25C3 Conference on Agile System Administration . He has also created a google group "Agile System Administration" where you can further discuss these ideas. Way to go Marcel!
