[Impact]
See this issue for details https://github.com/systemd/systemd/issues/2037
Basically, while DAD is running checks on a ipv6 address, no service can
bind the interface, which could provoke units to fail. Disabling DAD is
a workaround as explained here [1], but ideally systemd should wait until
the tentative flag is removed. v232 doesn't have this issue. Can the relevant
patches be backported to LTS releases?
[Test Case]
1. Configure ipv6 address on one interface
2. Create unit with After=network-online.target and pings a host over
ipv6
3. Restart the system
[Regression Potential]
* Unknown
[Other Info]
* Seems to have been fixed on v232.
* Using ifupdown or networkd to create the interface seems to be irrelevant
(upstream bug report uses networkd, while I use ifupdown)
