Bug#869995: interface stays in "routable (configuring)", systemd-networkd-wait-online.service in failed state

[Marc Haber]

retitle #869995 networkd gets wedged if more than one IPv6 address configured
thanks

Hi,

I took the opportunity to learn about stateless DHCPv6, while I was
still thinking that it is static configuration of additional IPv
addresses that causes the issue. Unfortunately, this is not the case,
and systemd-networkd also gets wedged when a second IPv6 address
additional to the one coming in via SLAAC comes in via DHCPv6.

And I also noticed that systemd-networkd gets wedged so badly that even
no DHCPv4 is happening, leaving the system with only the SLAAC IP (the
one that is unlikely to be in DNS).

I think this warrants an "important" priority, if not a release critical
one. Please consider that.

Greetings
Marc
