Darrick,
Thanks for the response. I'm sorry to be using up so much list bandwidth
today.
I *think* that's a bit different than I'm seeing. I stumbled across this
issue with the vanilla setting for IPV6 in rc.conf (commented out). I then
tried uncommenting it and setting it to NO (IPV6=NO), to no avail. The test
in the network (etc/init.d/network) script made it pretty clear that it
needs to be either NULL or undefined.
You said you verified it, and I certainly believe you. I've just got to see
what the difference is between the two environments.
What I'm seeing is that the module ipv6 is already loaded when I come into
the network script. (see below).
A simple question is as follows:
If IPV6 is commented out in rc.conf, then should ipv6 be loaded ?
======================================
# IPv6
echo "ipv6 is $IPV6..."
modprobe -l ipv6
if [ -n "$IPV6" ]; then
echo "loading ipv6..."
modprobe ipv6
else
echo "removing ipv6..."
modprobe -r ipv6
fi
modprobe -l ipv6
================================
produces
================================
ipv6 is ...
/lib/modules/2.6.20.21-astlinux/kernel/net/ipv6/ipv6.ko
removing ipv6...
/lib/eth2: link up, 100Mbps, full-duplex, lpa 0x45E1
modules/2.6.20.21-astlinux/kernel/net/ipv6/ipv6.eth0: link up, 10Mbps,
half-dup1
ko
=================================
I'll keep digging for insight into this.

Ron,
I've confirmed two things. If ipv6 is NOT enabled, ntpd runs fine.
(restart did not work--fixed in SVN 2131).
You would also have to have IPV6=YES uncommented in rc.conf (it's not
used by default). If you enable IPV6, ntpd does indeed fail.
