Subject: ISC-DHCPD in a OmniOS zone

Hello, as per subject line, I'm trying to set up DHCPD within a zone,
which is somewhat like a BSD jail -- a shared-kernel isolated chrooted
execution environment.
The environment has three interfaces which it inherits from the 'real'
running OS environment:
root@diener:/root# ifconfig -a
lo0:2: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g1:2: flags=1100943<UP,BROADCAST,RUNNING,PROMISC,MULTICAST,ROUTER,IPv4> mtu 1500 index 2
inet 192.168.1.2 netmask ffffff00 broadcast 192.168.1.255
lo0:2: flags=2002000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL> mtu 8252 index 1
inet6 ::1/128
When I attempt to start isc-dhcpd:
root@diener:/root# /usr/sbin/dhcpd -cf /etc/dhcpd.conf -lf /var/db/dhcpd.leases -f -d -p 67 -s 255.255.255.255 e1000g1:2 e1000g1
binding to user-specified port 67

Obviously that third interface, the lo0:2 ipv6, is the problem but I
don't want the serve dhcpd on that interface anyway. As my dhcpd
command line indicates, I'm specifying the interface on which I want
dhcpd to listen, but it doesn't make any difference --- dhcpd still
attempts to look at the lo0 interface, fails, and bombs.
It doesn't matter what interfaces are given on the command line
(including none); the error is always the same.
Any ideas? Really it seems to be necessary to stop isc-dhcpd from
looking at that lo0 interface at all.
