>Description:
The jail command doesn't reverse the order of fstab when dismounting.
>How-To-Repeat:
# cat /etc/jail.conf
exec.start = "/bin/sh /etc/rc";
exec.stop = "/bin/sh /etc/rc.shutdown";
exec.clean;
mount.devfs;
path = "/jails/${name}";
mount.fstab = "/etc/fstab.${name}";
host.hostname = "${name}.FreeBSD";
build {
interface = "fxp0";
ip4.addr = "10.0.0.1";
allow.raw_sockets;
}
