Hi,
Similar to issue 73873 [0], I'm also seeing ntpd segfaults at boot and
it looks to be due to ipv6:

It's been doing that since around the time of issue 73873 [0]. I double
checked and it does use the 2.guix.pool.ntp.org pool. I also reverted back
to 0.guix.pool.ntp.org in case for some reason that would work. Both
segfaults ntpd. Did 2.guix.pool.ntp.org stop supporting ipv6?
Thanks
