Well, I think you're right... Not all the time this error message loops.. I tried to start it 5 minutes ago and I saw a blue screen with a working mouse cursor (for about 2 seconds) and then I saw something like "Crash Report" and it keeps looping between this report and the blue screen (BTW, not the famous Microsoft blue screen)..

By the way.. for everyone who gets this error message try the following:

boot with -s
mount -uw /
mv /System/LaunchDaemons/mDNSResponder* /

(i believe.... i'll check in a minute)
This worked for me.. at least.. for the looping of the mDNSResponder error...

@Zephyroth: I too got this message earlier with other installs, but it didn't loop through this message.. Now it does.. what could this mean??
