While it'd be nice to understand why ntpd segfaults when the server
doesn't support IPv6, this is now mitigated by using an IPv6-enabled
pool address by default (see: commit 503919fcf0 ("services: ntp: Default
to an address that supports IPv6.")).

Closing for now.

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.
