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 :-)
The easiest way to find out is to try it.
Sorry, try what? :-?
Try to reach an IPv6 address.
It fails, obviously.
Now it (chrony) knows that address could not be reached. Good.
I got a default network install with a default chrony install, and it does try to use Ipv6, on Leap 15.2
Good.
No, bad, as we determined there is no IPv6 and that the program (chrony) should know it as there is no routeable IPv6 address.
I'm stopping here, this talk is only creating superfluous noise, and we are not getting anywhere.
