And openSUSE machines get/create a linklocal(?) IPv6 addresses, so it seems that programs inside think that IPv6 is available:

On a machine with LL only, any application that attempts to connect to a non-LL IPv6 address will receive a "network unreachable" error and just needs to handle that.
Well, that is precissely my point! chrony should know that there is no IPv6 and not try it :-) -- Cheers Carlos E. R. (from openSUSE Leap 15.1 x86_64 (Minas Tirith))
