I just installed this on my FC3 laptop, accepting I think all of the default options.
1. I immediately became unable to access my local webserver (apache). This hurts, as I am a freelance web developer.
2. I tried restarting and can no longer boot this machine. That is definitely not going to work for me.
bootup display hangs at "Starting zimbra"
Also for some reason I cannot enter "interactive startup", which I would like to do, in order to tell it "Please don't start Zimbra!"
