           Summary: make unprivileged mode default under certain
                    conditions
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
        AssignedTo: systemtap@sources.redhat.com
        ReportedBy: fche@redhat.com


For a stapusr person invoking stap, the translator should
probably default --unprivileged --use-server, since that's
the only way the stapusr will get anywhere.

I would agree that, currently, --unprivileged is the only useful mode for
stapusr members when it comes to loading their modules, however, for phases
1-4, why restrict them?

- they may benefit from compiling script beyond the scope of --unprivileged for
  the purposes of learning about stap or out of curiosity.
- they can benefit from being able to list probe points beyond the scope of
  --unprivileged for the same reason

With respect to --use-server, it may be useful for stapusr members to have stap
check their scripts locally, either for efficiency or when a server is not
available.

And what about completely unprivileged users (i.e. not even a member of
stapusr)? Are we not planning on someday removing the restriction that
--unprivileged users must be members of stapusr?
