bug#73873: ntpd segfaults at boot (caused by use of IPv6?)

[Maxim Cournoyer <maxim.cournoyer@gmail.com>]

Hi,

After adjusting my system time in UEFI, I've had the ntpd daemon
terminate with exit status 11, with the following message in
/var/log/messages:

I've had to do:

# herd enable ntpd
# herd start ntpd

To have it run again after the boot was completed.
