I have never seen audit itself causing kernel crash but I sometimes need to see audit logs to get any hint to know what was happening on the crashed system in the timing of crash. > > Anyway, I definitely don't see it as a top-level built-in command.

I think log command is best suited in meaning for audit logs. By the way. I don't understand why you listed ps command first. I don't find any similarity to ps command with audit. -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/crash-utility
