            Bug ID: 230687
           Summary: rmuser kill_procs kills processes in jails
           Product: Base System
           Version: 11.2-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs@FreeBSD.org
          Reporter: simon@ikanobori.jp

The usr.sbin/adduser/rmuser.sh script which ends up in /usr/sbin/rmuser when
ran from a host system such as `rmuser user` will kill all processes owned =
by
`user` in its kill_procs routine by identifying processes with `ps -U $USER=
`.

This includes jailed processes which is not something to be expected (or is
it?).

I could submit a patch which would remove processes which have a J flag hid=
den
behind an argument such as --no-jail / -F but don't know if this is desirab=
le.

It doesn't seem there are much better options here as we can't get the curr=
ent
JID as far as I'm aware. If that were possible we could add the -J $JID fla=
g to
ps.
