nullfs in FreeBSD jail

[Boris Samorodov]

Hi!


I'm installing ports-mgmt/tinderbox at a FreeBSD jail. Distfiles 
(/usr/ports/distfiles) from the host nullfs'ed into the jail. Now I
want tinderbox to use nullfs for distfiles (i.e. distfiles from the
FreeBSD jail nullfs to ${tc}/portstrees/...). But I get:
"mount_nullfs: Operation not permitted".

The host:
-----
% uname -a
FreeBSD and.ipt.ru 7.0-CURRENT FreeBSD 7.0-CURRENT #5: Fri Jul 20 18:48:45 MSD 2007     bsam at and.ipt.ru:/ms/usr/obj/usr/src/sys/GENERIC+ULE3.0  amd64
% sysctl security.jail
security.jail.jailed: 0
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

Thanks!
