I hope you don't mind giving me some advise on my partitioning set up since I am going to install cpanel whm. I have been searching for partitioning set up and have found the cpanel tips website. BUT, I am left puzzled why as setting up my partitioning in red hat 9 text mode, I was given this partitioning setup. Will you kindly be glad to offer assistance?
Ahh, the joys of working on hardware based in the 80's...
You are limited to four primary partitions on a PC based system. In your case hda4 is an "extended" partion that can itself have partitions. You'll never directly interact with hda4, only the child partitions hda5 - hda8.
Basically you're ok. It's just the fact that there can only be four primary partitions that makes it a bit confusing.
The only way to delete an extended partition is to first delete all of the sub-partitions first. Really, I think your configuration is ok. I personally always have a /usr/local partition but that is a matter of taste, not a requirement.
