4.2. acpid

Prior to this update, the acpid daemon repeatedly wrote a number of CPU events to the /var/log/acpid file on certain hardware that was set up for high performance. With this update, the acpid daemon has been optimized so that the CPU events are no longer logged to /var/log/acpid.

The acpid package contains a trigger scriptlet that returns a non-zero exit code if the /var/log/acpid log file does not exist. Prior to this update, if the acpid daemon was installed but never started on the system and the /var/log/acpid file did not exist, the scriptlet did not function properly and caused the package update process to fail, which could have resulted in two different acpid packages being installed on the system and registered with the RPM database (rpmdb). With this update, the acpid package has removed the spurious acpid record from rpmdb so that the problem is now fixed.
