Specifically, this product is forked from the source code for Red Hat's _Red Hat Enterprise Linux 3_ product under the terms and conditions of it's EULA.
There may be remaining packaging problems and other odd bugs. These are solely the responsibility of the White Box Linux effort and should not in any shape, manner or form reflect on the quality of Red Hat's commercial product. In fact, if you need a fully tested and supported OS you probably should go buy their box set.
A fair amount of effort has gone into removing Red Hat's trademarks and logos. Should you find one remaining, please report it so that it can be removed.
The goal of this project is to provide an unencumbered RPM based Linux distribution that retains enough compatibility with Red Hat Linux to allow easy upgrades and to retain compatibility with their Errata srpms.
Being based off of RHEL3 means that a machine should 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.
