mount_nullfs inside a jail

Hi!


Is it possible to use mount_nullfs inside a jail?

With amd64-current:
-----
# sysctl security.jail
security.jail.jailed: 1
security.jail.mount_allowed: 1
security.jail.chflags_allowed: 1
security.jail.allow_raw_sockets: 0
security.jail.enforce_statfs: 2
security.jail.sysvipc_allowed: 1
security.jail.socket_unixiproute_only: 1
security.jail.set_hostname_allowed: 1
# mount_nullfs /usr/ports /mnt
mount_nullfs: Operation not permitted
-----

Thanks!
