Description of problem: Reference guide contains detail specification about rhel4 clients data structures. Unfortunately RHN client logs and cached information has changed slightly over the years. * /var/spool/up2date is in no longer in use - On rhel5 and above we may want to refer to /var/cache/yum instead * /var/log/update is not used by gui applets on newer rhel * Older logs of /var/log/update are named differently on rhel6 - 'up2date-20101129' instead of 'up2date.1' * Default rpm gpg key path has been changed - rhel3/4: /usr/share/doc/rpm-4.1/RPM-GPG-KEY - rhel3/4: /usr/share/rhn/RPM-GPG-KEY - rhel5/6: /etc/pki/rpm-gpg/ (the last one is not documented) Version-Release number of selected component (if applicable): RHN Satellite 540 Reference Guide + possible other guides
