This isn't relevant to LPI, but I'll address it. The Red Hat Network (RHN) is Red Hat's legacy subscription management platform. RHN Satellite (Server) is the productized version of of the service. It was largely the answer to corporate needs to manage and distribute internally. It also has custom software and configuration channels, kickstarts, etc... Red Hat open sourced it at this year's summit in June. Naturally that means the full source code is available under the Fedora brand. So RHN Satellite is now available as Fedora Spacewalk, named so by Michael DeHann (if I hear correctly at FUDCon first-person from Michael himself). CentOS made an announcement regarding their adoption the same week. In a nutshell, as I stated before, RHN and the productized Satellite, are very legacy implementations - some 8+ years old now. It is a mix of original Oracle DB, Java and Perl, with Python added. Most of the original RHN developers are core Fedora mainstays. E.g., GDK is Fedora Community dodo #1, and the infamous "Tito" in RHN lore. Michael DeHann is the guy behind Cobbler, a new provisioning system. A sister endeavor to Cobbler is Koan, an key enabler for Xen/KVM in Fedora/RHEL. There are many other Fedora/Red Hat employees involved in Fedora/Red Hat "emerging technologies" (ET), of which more and more is being integrated. Configuration management is also a major ET detail - puppet being a new one. Most of these ETs augment and even replace a lot of legacy compnents in Sat. So as the Fedora Spacewalk integrates them, you'll see the RHN Sat product add them. Red Hat, in general, hates to use anything that is not flushed out in the community anyway. And RHN was the only codebase/product they had not released to the community. I know a lot of people were glad to see it finally done, especially those who wrote it. In reality, it was an on-line service, hacked together, turned into a product, now legacy. It's lineage is the exact opposite of how Red Hat normally operates. -- Bryan J Smith - mailto:[EMAIL PROTECTED] http://thebs413.blogspot.com Sent via BlackBerry from T-Mobile
