The directories in this top directory are labelled according to the Fedora Core distribution on which the packages have been built. Thus for example, the "2" is the one in "Fedora Core 2" and is according to RedHat convention for the Fedora trees. I thought to start dividing packages for distributions since I expect that there will be changes according to that, hopefully not too many for kernel and rsbac-admin, but surely for my scripts. At the moment anyway the directories division just means that I built the packages on the Fedora Core N distribution, but they could work on other (future) Fedora or other distributions as well like RHEL.
