To provide an unencumbered RPM Based Enterprise Linux distribution that retains enough compatibility with Red Hat Enterprise Linux (version 3 and beyond) to allow easy upgrades and to retain compatibility with their errata srpms. being based off of rhel3 means that a machine shocould be able to avoid the upgrade treadmill until Oct 2008 since RHEL promises errata availability for five years from date of initial release and rhel3 shipped in Oct 2003.
Or more briefly, to fill the gap between fedora and RHEL.
Clearly stated on the white box Linux (http://whiteboxlinux.net/) site:
Red Hat did not build rhel3 from the published srpms. period, end of story. they didn't even build taroon from it's source. openSSL's srpm does not build the same binaries as the ones supplied in taroon and it is the same srpm as the one in rhel3. I'm porting in a copy from fedora which builds correctly. plus the package set is not self sufficient to actually build itself, several additional srpms Need to be tracked down. Intentional GPL violation or carelessness? I'm reporting, you decide.
Digress: Red Hat ambition Lu xiaoa. Who knows whether the company will become the second Microsoft in the opensource field? However, as long as there is monopoly, there will be opponents.
