What is this Fedora Core 1 thing?
Read the official page a bit. Now, I’ll give you a brief rundown — You can think of Fedora Core 1 as something like Red Hat Linux 10, except: • It’s now a community project. Its development happens on public mailing lists. See the Fedora website for more about this. • Official support is only provided from the Fedora Project for 6 – 8 months per version. This means upgrading your OS every 6 – 8 months. The upgrades should be relatively painless, much like RH 8 – RH 9. The painlessness is not guaranteed. • If you don’t want to upgrade every 6 – 8 months, there is something called the Fedora Legacy Project which hopes to patch in important security fixes to unsupported Fedora builds for as long as possible. • Fedora Core versions are released on a time schedule, instead of When They’re Ready (TM).
