The details do matter here, as some applications (ex: openvswitch) have specific policies on which files files get opened and where those files exist. That has impact on things like selinux and other access control technology. If I missed the API that lets apps redirect the output, please correct me, but so far I don't think I've missed it. pdump still can change a default, but it would be good to give a method for guiding the final choice of file to open. -Aaron
