rbldnsd does not start in a jail

Hello.

I'm running rbldnsd in a jail since a long time.
Lately it fails to start:
> service rbldnsd start
> Starting rbldnsd.
> rbldnsd: listening on 127.0.2.1/10053
> rbldnsd: unable to chroot to /usr/local/etc/rbldnsd: Operation not permitted
> /usr/local/etc/rc.d/rbldnsd: WARNING: failed to start rbldnsd

I had to change "-r" to "-w" in rc.conf's rbldnsd_flags in order to 
disable chrooting.

I'm not sure if this started since I upgraded from 14.0 to 14.1; looks 
like rbldnsd itself didn't change recently...

Any comment?
Was chroot in a jail disabled recently? Is some additional setting 
needed for 14.1? I didn't find anything in the release notes.
Perhaps it does not make much sense to chroot in a jail?
Is this a bug worth reporting?

  bye & Thanks
