Today, at the Red Hat Summit in Boston, Mass., Red Hat introduced Project Spacewalk. RHN has provided patches and software for Red Hat Enterprise Linux operating system. Spacewalk is an open source (GPLv2) Linux systems management solution. It is the upstream community project from which the Red Hat Network Satellite product is derived. From the press release:

Spacewalk is the upstream project upon which RHN Satellite will now be based. Spacewalk will work with Red Hat Enterprise Linux, Fedora and other Red Hat Enterprise Linux derivative distributions like CentOS and Scientific Linux. Spacewalk will bring together a growing community of new users along with seasoned systems management veterans. In this way, the Satellite product can grow (as Linux itself does) with the combined efforts of the open source leader, Red Hat, and an invigorated community. Both will work together to expand the capabilities and stature of the upstream project. This will translate into faster adoption of new, innovative ideas and technologies into the downstream Satellite product.
