[Zope] Zope and Linux flavors

Howdy Zopistas! These days I came to the conclusion that I might need to investigate a bit on Linux as an alternative base for running Zope. So far I've been using OpenBSD which is a real timesaver when it comes to setting up a secure server which is my first priority over anything else. What I'd like to know is: Which Linux distributions are you using for running Zope and how easy it was for you to maximize security of your server? Ragnar
