Slackware, LFS and (soon to be gone) Suse.
My 2 favorites aren't in the list
I really like LFS. It's perfect to set up your own environment, you have total control and it's a great way to learn a lot about linux.
If that's (still) a little too hard or you don't want to spend the time it takes to set up LFS, Slackware is a very good pre-packaged distro. Started using Slackware about 3 months ago (Suse started to irritate me
) and I'm planning to re-install my server with Slack.
Suse was my first linux distro, back then a perfect distro to start with. I guess that right now I would start with Knoppix (use that as a rescue CD atm). If you want to use distro in a professional environment I would recommand either Suse or Red Hat, those are used most atm.
Might have read it a different way then you intended.
Ok, Linux 2.4.19, 2.4.24 (2X), 2.4.23
