[FreeBSD-users-jp 96386] jail に devfs_ruleset が反映されない

[小野寛生]

小野寛生です。

stable/12 r344791 で vnet jail を動かしているのですが、jail.conf で指定したルールセットが反映されておらず、
デフォルト(0) の状態になって、jail 内でも /dev 以下がすべて見えてしまっています。
また、host で

jail -n gate -m devfs_ruleset=12

とやっても jail の security.jail.devfs_ruleset の値が変化しません。
何か設定ミスがあるのだと思いますが、devfs_ruleset を反映するにはどうすればよいか教えてください。
jail.conf と devfs.rules は下記のようになっています。

==================== jail.conf =====================
devfs_ruleset = 12;
# enforce_statfs = 1;
allow.mount;
allow.mount.devfs;
allow.sysvipc;
vnet;

host.hostname = "${name}.oikumene.ukehi.net";
path = "/usr/jails/${name}";
exec.clean;
exec.consolelog = "/var/log/jail_${name}_console.log";
exec.system_user = "root";
exec.jail_user = "root";
mount.fstab = "/etc/fstab.${name}";
mount.devfs;
mount.fdescfs;
mount.procfs;

$ifconfig = "/sbin/ifconfig";
#$rotate = "";

exec.prestart += "${ifconfig} epair${ifa}a up";
exec.poststart += "${ifconfig} epair${ifa}b vnet ${name}";
exec.poststart += "jexec ${name} ${ifconfig} epair${ifa}b inet ${ip4addra}/24 up

";

exec.prestop += "jexec ${name} /bin/sh /etc/rc.shutdown";
exec.prestop += "${ifconfig} epair${ifa}b -vnet ${name}";
# exec.poststop += "${rotate} /var/log/jail_${name}_console.log";

gate {
        devfs_ruleset=11;
        allow.raw_sockets;
        securelevel = 2;
        vnet.interface = "ue0";
        $ifa = 0;
        $ip4addra = 192.168.8.1;

        $ifb = 3b;
        $ip4addrb = 192.168.9.1;
        vnet.interface += epair${ifb};
        #exec.poststart += "${ifconfig} epair${ifb} vnet ${name}";
        exec.poststart += "jexec ${name} ${ifconfig} epair${ifb}
${ip4addrb}/24 up fib 1";
        exec.prestop += "${ifconfig} epair${ifb} -vnet ${name}";
        exec.prestop += "${ifconfig} ue0 -vnet ${name}";
}

inner {
        depend = "dc";
        $ifa = 1;
        $ip4addra = 192.168.8.2;

        $ifb = 4b;
        $ip4addrb = 192.168.9.2;
        vnet.interface += epair${ifb};
        #exec.poststart += "${ifconfig} epair${ifb} vnet ${name}";
        exec.poststart += "jexec ${name} ${ifconfig} epair${ifb}
${ip4addrb}/24 up fib 1";
        exec.prestop += "${ifconfig} epair${ifb} -vnet ${name}";
}

dc {
        $ifa = 2;
        $ip4addra = 192.168.8.3;
}

exec.poststart += "jexec ${name} /bin/sh /etc/rc";
