5.3-RC1: jail + bind9, devfs rule: ioctl DEVFSIO_RAPPLY: Inappropriate ioctl for device

Hi,

i have upgraded from 5.2.1 to 5.3-RC1. Bind8 runs fine in jail
environment. I have migrated as described in /usr/src/UPDATING.

Bind9 runs fine, too. But i when jail starts with "named_enable="YES""
in /etc/rc.conf, i see:

[...]
Starting syslogd.
mount_devfs: Operation not permitted
devfs rule: ioctl DEVFSIO_RAPPLY: Inappropriate ioctl for device
devfs rule: ioctl DEVFSIO_RAPPLY: Inappropriate ioctl for device
devfs rule: ioctl DEVFSIO_RAPPLY: Inappropriate ioctl for device
Starting named.
Clearing /tmp.
[...]

at startup. With "named_enable="NO"" there are no devfs rule:
ioctl... messages.

Bind 9 runs, logfiles looks good and i have no devfs rules, but
maybe errors on jail startup pointing to another problem.  Anyone
knows what happens here?

bye,
Andy
