            Bug ID: 16725
           Summary: stap should warn when system wide process probes are
                    used with --runtime=dyninst
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dyninst
          Assignee: systemtap at sourceware dot org
          Reporter: mjw at redhat dot com

When using --runtime=dyninst process probes are target only, not system wide. 

stap should warn about that if no -x or -c target has been given instead of
silently running in pass 5 without feedback on why no probes fire.

--- Comment #1 from Josh Stone <jistone at redhat dot com> ---
stapdyn knows the probes in the module, since it's the one who will perform
instrumentation, so it could easily fire a warning when it lacks -x/-c.  This
way we can warn even when someone runs stap --dyninst -p4, followed by manually
running stapdyn.
