(In reply to Elizabeth Myers from comment #2)

Wait, are you saying that procstat executed from *outside* the jail shows t=
he
full paths (which is expected), or that procstat executed *inside* the jail
shows the full paths (which I can't reproduce)?

The code path at issue uses vn_fullpath which is sensitive to the root
directory of the invoking process, i.e. procstat, not to that of the process
being examined.

If you're finding that procstat from *inside* the jail is showing the full
path, can you show a complete session transcript including the jail creation
and execution of the procstat command?
