Yesterday I participated in a round table for Red Hat on how to best deliver training for RH and RDH.
Easy, simply direct your trainees to
http://www.slackware.com/ I've had bad experiences with Red Hat and Fedora. They are just too much of a departure from traditional *nixes for me. Building anything from source on Fedora is a real pain (more so than usual). I find even BSDs closer to *nix than Fedora.
The one piece of advice I can give is to tell new users to turn off the automatic filesystem search index. If you unpack a few source distributions, build them and try to run a server then watch as the machine is I/O bound by the search index grinding the disk constantly. Perhaps they have had the sense to disable it by default since I last worked with it in 2003.
Besides, the whole "Pro" version leaves a bad taste in my mouth. That's not OSS by my definition. Uless Red Hat is available for free now? Or is it just the buggy beta testbed known as Fedora? (sorry, had to vent there.)
