The "clearos-core" repository is now version 6.6 (though one of the packages failed to rebuild). If you have it enabled, you will be getting the upstream 6.6 updates. It would be nice to have a public "clearos-core-testing" repository, but that hasn't happened yet. Since the "clearos-core" repo is for command line hackers only, it is perceived to be not commercially important to ClearOS Professional subscribers. Though I don't like the policy, I know that it's all balance between resources and keeping customers happy.
In a strange twist, the move back to CentOS in ClearOS 7 means that "core" (aka CentOS) updates will be handled through a more thorough QA process.
could someone confirm my thinking - I envisage that 6.6 might 'auto install' as per a patch update onto my 6.5 box with no intervention (with auto update on), whereas for version 7 we would expect to have to manually initiate the installation /upgrade?
My 'guiding principle' for COS is that it should be a replacement (and more) for Windows Small Business Server 2003 as this was the last 'out of a box' solution for <100 users, and their needs are just as relevant today. The mentioned Spacewalk application looks like it is fairly cool, but I think this ventures into the 'large corporate enterprise' and at this point in time is probably a bit beyond the scope of the COS professional editions.
