I pasted it at the end of this email as it is a bit long.

I agree! At first I thought it was related to a Perl problem but now I know 
better.

Yes.

Nothing. When I have the FAILED error starting apache nothing gets appended 
to those files.

Hum . . . no file called hostname on my system then. Is that a Bad 
Thing[tm]?

Ok. No more assigning localhost to ips besides 127.0.0.1 :)

Yes I do. But my machine has private IP address so no resolution should take 
place, I hope.

Makes sense. But where is it stored now? I definitely have to get that 
fixed.

Ok. If I understand your logic this means that all machine with IPs (even 
private ones) must put an entry in /etc/hosts?
