Now, if you're not sure which distro you like better, here are a few notes from my evaluation of RH9 over the past few days.
- More consistency of system file locations
- Single, very good packaging system (apt)
- Easier to find packages if they exist.
- System scripts make more "sense" to me.
- Keeping system up to date with patches is free.
- One distro for desktop and server.
- Fewer packages (though you can use alien to convert .rpm to .deb, you always run the risk of breaking something)
- Stable distribution of Debian lags way way behind.
- No official vendor hardware or software support
RedHat 9 Pros:
- More packages
- Packages are MD5 signed
- Nice graphical admin tools (you may not care)
- Good integration with Gnome and KDE desktops
- Multiple packaging systems (up2date, yum,apt) are confusing.
- RedHat has only just now got automatic dependency resolution with apt and yum.
- RedHat patches the heck out of their kernels. I'm assuming they do QA testing before they release such heavily patched kernels, but even so they get far less testing than a stock kernel.
- Future of "free" Red Hat is in question right now. "Free" Red Hat is now called "Fedora Core". Red Hat will *not* offer support for Fedora. See http://fedora.redhat.com/ for more information. Basically they are trying to create a Debian-like system where many people could contribute packages. Fedora will be the proving ground for new technologies to eventually go into ES/AS.
The *only* reason we would switch to RH is support. Vendors are getting tighter and tighter about support for Linux, and who can blame them? It's not enough for them anymore for you to just tell them "I'm running Linux, kernel 2.4.21".
Actually, I just thought of one more reason to use RH--if you purchase a server from a vendor that offers RH preinstalled. If that is the case, then you should stick with RH. We just went through a horrible time with a vendor trying to figure out what was wrong with one of our servers. Fortunately he never said "well I only certify my boxes with RH", but a large vendor (Dell? HP?) definitely would.
In another case I replaced a default RH install with Debian on another server at a remote colo, and then RH released a technical advisory for the RAID controller on the box. They offered to send a tech to flash the firmware on the card and update the SCSI driver to go with it. When the tech arrived he realized that if he tried to boot the box with the RedHat patch CD he very likely would render the machine unbootable because the machine didn't actually have RH on it. Fortunately we realized this in time.
Don't get me wrong, I LOVE Debian. I'd hate to leave it, but the Red Hat install base is reaching critical mass.
The Fedora thing really worries me. Lots of RH advocates are saying "don't worry, it is just opening up the development and Fedora packages should always work on AS/ES, and vice versa", but time will tell. Before Fedora I wasn't worried because you could always guarantee that the "Free" and the "Pay" versions of RH were pretty close. Now I think Fedora is going to zip way out in front of AS/ES.
I've rambled enough.
