If dump target is ipv6 address, a host should have ipv6 address ready before starting kdump service. Otherwise, kdump service fails to start due to the failure "ssh dump_server_ip mkdir -p $SAVE_PATH". And user can see message like: "Could not create root@2620:52:0:10da:46a8:42ff:fe23:3272/var/crash" I observe a long period (about 30s) on some machine before they got ipv6 address dynamiclly, which is never seen on ipv4 host. Hence kdump service has a dependency on ipv6 address. But there is no good way to resolve it. One way is asking user to run the cmd "nmcli connection modify eth0 ipv6.may-fail false". But this will block systemd until ipv6 address is ready. Despite doing so, kdump can try its best (wait 1 minutes after it starts up) before failure. How to implement the wait is arguable. It will involve too many technique details if explicitly waiting on ipv6 address, instead, just lean on 'ssh' return value to see the availability of network.
