Ok, this jail setup thing is slowly driving me mad.  Can someone
explain the following behaviour observed on a jail (hll124) set up
using ezjail?

root@hll107:~ # sysctl security.jail.allow_raw_sockets
security.jail.allow_raw_sockets: 1

root@hll107:~ # service local_unbound onestatus
local_unbound is running as pid 76810.

root@hll107:~ # drill vhost04.hamilton.harte-lyne.ca
