- non-IIIMF input methods - they are now obsolete for a few releases
Input methods are a big annoyance to people who don't use them; when we installed RH 9 on my sister-in-law's computer, her first complaint was that it "took too long to boot." I went in and cleaned up the boot sequence and found that a number of different input methods that I'd never heard of wasted many seconds at boot time.
- mozilla (classic) - superseded by firefox, thunderbird, epiphany, etc
I have no idea why the world has embraced firefox after rejecting mozilla. Perhaps there's a hidden way to do it, but I've had much better luck configuring the pop-up blocker in mozilla... The are lots of little features in mozilla I find myself missing in firefox.
On the other hand, RH always seems to ship a Mozilla that's hopelessly out of date so I usually end up installing my own in /usr/local and rpm --erasing the one that came with the OS. (Funny enough, I do that for all of the software that I actually care about.)
