Previously, the "explain_syslog" and "syslog_to_svclog" commands failed with a "No such file or directory" error message. With this update, the ppc64-diag package specifies the location of the message_catalog directory correctly, which prevents the described error from occurring.
Prior to this update, the /var/lock/subsys/rtas_errd file was incorrectly labeled for SELinux as "system_u:object_r:var_lock_t:s0". This update corrects the SELinux label to "system_u:object_r:rtas_errd_var_lock_t:s0".
Users of ppc64-diag are advised to upgrade to these updated packages, which correct these issues and add these enhancements.
