Aha :)  Some manual setup is expected before starting/entering the jail:

    # Linux-like /proc and /sys filesystems
    mount -t linprocfs linprocfs $JAIL_ROOT/proc
    mount -t linsysfs linsysfs $JAIL_ROOT/sys
      
    # Ramdisk required for /run
    mount -t tmpfs tmpfs $JAIL_ROOT/run
    
    # A read-only /dev filesystem with restricted set of devices
    mount -t devfs devfs $JAIL_ROOT/dev
    
    # Compatibility symlink from /dev/shm to /run/shm
    ln -s /run/shm $JAIL_ROOT/dev/

I'm not sure if 'shutdown' is really expected to work yet in jails;
this is still quite experimental.

An alternative is to manually execute inside the jail:

    /etc/init.d/rc 0
    exec kill -1
