            Bug ID: 31060
           Summary: Early uprobe registration and task-finder target
                    executable path resolving should switch mount
                    namespace to the target process's
           Product: systemtap
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: runtime
          Assignee: systemtap at sourceware dot org
          Reporter: agentzh at gmail dot com
  Target Milestone: ---

When --target-namespace=3DPID is specified, the early uprobe registration a=
nd
target program file path resolving in task finder fail to switch the current
mount namespace to the target program's.

Otherwise we'd see errors like this:

```
ERROR: Couldn't resolve target program file path '/newroot/a.out': -2
```

I'm preparing a patch to address this issue.
