            Bug ID: 230487
           Summary: jail -m works incorrectly in some cases
           Product: Base System
           Version: 11.2-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs@FreeBSD.org
          Reporter: jasonmader@gmail.com

It looks like a `jail -m` is not correctly handling jail.conf and then sets
incorrect values to a running jail. Example, here the `php` jail is getting=
 the
wrong hostname, ip6 address, and devfs ruleset.

root# jls -a
