Sub Tasks
JDK-8273131 :  
Update the java manpage markdown source for JFR filename expansion - Open
Description
Unified logging allows user to specify %p and/or %t in the filename, which will expand to the JVM's PID and	startup timestamp, respectively.

We should consider something similar for -XX:StartFlightRecording and JFR.start.
Comments
The manpage changes associated with this issue were lost because they were never applied to the closed markdown sources. A subsequent regeneration of the manpages, JDK-8273179, caused the new information to be lost, and this was unfortunately not noticed at the time. So the documentation for this has never been present and remains absent until JDK-8273131 is fixed.
