What is this Fedora Core 5 thing?
First, read the official Fedora page a bit. Now, I’ll give you a summary. You can think of Fedora Core 5 as something like “Red Hat Linux 14,” except it differs from the old Red Hat Linux in the following ways: • It’s a community-supported project. That means that you can be involved in creating Fedora Core, if you want. • A new version of Fedora Core comes out every six months. • When a new version comes out, the previous version becomes unsupported after another 6 – 8 months. This means upgrading your OS every 6 – 8 months. The upgrades are usually very easy, much like Red Hat Linux 8 – Red Hat Linux 9. The easiness is not guaranteed. If you don’t want to upgrade every 6 – 8 months, there is something called the Fedora Legacy Project. They provide security patches for each version of Fedora for an additional 1 1/2 years after the Fedora Project stops their support. Red Hat Enterprise Linux is based on Fedora Core, so if you want to learn a little about RHEL for free, use Fedora Core.
