I'm a little confused about what you are supposed to do when you discover a bug with CentOS (and by implication RHEL). Is there some policy as to what to do and where to report the bug? It doesn't seem appropriate to report it to http://bugs.centos.org because CentOS is kept in-sync with the upstream, so bugs will never get fixed in CentOS, only in the upstream distribution. Unless there is some feedback mechanism from this CentOS bugtracker to Redhat that I am unaware of. So that makes the obvious place to report any bugs http://bugzilla.redhat.com, but do they (Redhat) have any opinion on people reporting bugs observed on a CentOS distribution there? Do they welcome it or do they discourage it? There is certainly no CentOS product classification in their bugzilla I can see. So, in short, is there any CentOS bug reporting policy, and is it written down anywhere? Hywel.
