Gotchya. Cool.
Personally, with each edition of Red Hat, I buy one copy just to support the company. I've never found a need to use their tech support.
You prolly could BE their technical support. ;^)
Good on you for supporting them. Will do the same.
RedHat Linux 7.3 came up rather easily (about 1 hour) on my 3 homebuilt P4s. To play with the customization and modify via source code changes one needs to know about RPMs, which seems to be somewhat peculiar to Linux at this time. There is a RPM book out (forgot title) which gives you about 80% of what one would really want to know about RPMs. For setting up a server one tends to go outside the normal RH distribution and on the net (eg for wu-ftpd).
Hardcore Linux devotees prefer Gnome over KDE. I have tried both and both are buggy, with KDE being noticeably worse to the point of being (from my point of view) unreliable for everyday use. Gnome is better. This illustrates the principle that you generally want to follow the prejudices of the Linux hackers when presented with choices within Linux, since they tend to maintain the stuff they prefer better than the stuff they don't like. Mozilla is your basic mail interface (but I prefer BSD mail for transparency and simplicity over the visually oriented GUI cr*d).
Get a low end ATI Rage for the video card, it seems to be somewhat the defacto standard for Linux. If you like to listen to music and you are running an x86 with builtin sound device on the motherboard and RH 7.3, you'll need an auxiliary PCI sound card since RH 7.3 Linux doesn't recognize the motherboard sound device.
RedHat is trying to attract "Enterprise" class business and is succeeding here and there (especially in government institutions which have to be concerned about MicroSludge audits and associated formalities). My impression is that RedHat is hanging on financially by the skin of their teeth, narrowly avoiding the fate of VA Linux. They might make it financially but in any case the Linux base will carry on in some form or another.
