On one system I am missing /etc/log/rpmpkgs I believe that this file is updated by some cron job, and maybe I just have not had this system powered up at the right time for the job to run. Though I had thought that if a job was scheduled for a time the computer was off, it would run sometime soon (with some definition of 'soon') once the system was on again. On another system, I have /etc/log/rpmpkgs, but a rpm I installed from the karan testing repo is shown installed in /etc/log/yum.log but not in rpmpkgs.
