While it's a little awkward-looking, you can do something like this to make sure you've cleanly shut down and detached: exec.prestop =3D "/usr/sbin/jexec ${name} /bin/sh /etc/rc.shutdown"; exec.prestop +=3D "/sbin/ifconfig epair${ep}b -vnet ${name}"; exec.poststop =3D "ifconfig $bridge deletem epair${ep}a"; exec.poststop +=3D "ifconfig epair${ep}a destroy"; The notable thing is that exec.prestop and exec.poststop run in system=20 context, not jail context, so you need the jexec to execute the clean=20 shutdown - but it works. --=20 You are receiving this mail because: You are the assignee for the bug.=
