Yeah, I figured that having the AMD 64bit platform with a true 64 bit OS I 
would save some money instead of buying expensive SMP hardware from Intel...

And since Fedora is the only ready-to-use distribution from CD, rpm based that 
can be freely downloaded I was curious how it's doing :-)

OK, then this is certainly on my long term to learn list.

Say, how do you handle the short upgrade cycles of Fedora? Core 3 is nearing 
completion and it is only a matter of time until the Core 2 lifecycle reaches 
an end. Is upgrading to a newer Core release painless and can it be done 
without risking the availability of the services?
