I understand this better now. networkd actually went to handling DHCPv6/RA in userspace (https://github.com/systemd/systemd/commit/3b015d40c19) so that it actually *can* wait for IPv6 RA addresses -- if the kernel handles them, it does not know what to expect.
In yakkety we let networkd do that, but in xenial we revert it (https://anonscm.debian.org/cgit/pkg- systemd/systemd.git/tree/debian/patches/Revert-Revert-networkd-ndisc- revert-to-letting-the-k.patch?h=ubuntu-xenial) as networkd v229 has some regressions wrt. IPv6 handling compared to the kernel. These are fixed in 231, so we could drop the Debian reversion patch and instead backport these fixes. nplan and wait-online works fine with the patch dropped, for the record. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1627641 Title: Backport netplan to xenial To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1627641/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
