You might want to take a look at Debian for your Linux installation as well. I used to be a die-hard Redhat fanatic but after using Debian I wouldn't go back. No need to worry about dependencies when doing RPM installs. New version of PHP out, apt-get install php4. Or what I do is I just periodically run apt-get update and apt-get upgrade and it goes out and grabs all new versions of packages I am running and upgrades them. Makes maintaining my server soooo much easier.
