It seems that while DHCP6 doesn't return any error now and the DUID is the same after reboot and after network restart by our agent: DHCP6 Client DUID: DUID-EN/Vendor:0000ab118bf885a2ab7335a00000 it never gets a DHCP6 IP after network restart and the state stays in "configuring". Logs only show DHCPv6 lease lost IPv6 successfully enabled
This looks like a new issue. A new thread or even report in the issue tracker would be good. (At least it looks unrelated to overlayfs.)
and only a reboot fixes the problem. I think I'll probably just move on and remove ipv6 support from the kernel (as it seems that changing the default and all values from sysctl doesn't apply to networkd).
I think you can add `ipv6.disable=1` to the Linux kernel command line to achieve that, and that is respected by systemd-networkd (as it’s disabled in the Linux kernel) [1]. `ipv6.disable_ipv6=1` is ignored in my experience, because systemd-networkd writes to sysfs directly. (I have not analyzed that.)
