This seems like a good way to capture detailed debug logs at the time of error, without enabling debug logging all the time.  I would have a cron job to prune /var/lib/pacemaker/blackbox in case too many files are generated. 

Ah, you’re talking about the auto-dumping when we log an error?

There will be some impact, all the arguments need to be marshalled etc.
