I have a container sitting on a network with DHCPv4 and v6. Setting a static v4 address disables DHCPv4. Setting a static v6 address, does not. Per the systemd documentation, I need to set "IPv6AcceptRA=false" in the [network] section of the interface config do disable DHCPv6 addressing. Setting this manually works fine. However, it does not survive a reboot. Ideally, there would be a simple checkbox in the CT network config to enable/disable IPv6AcceptRA. Short of that, is there a way to inject that statement into the interface configuration at boot? https://www.freedesktop.org/software/systemd/man/systemd.network.html#IPv6AcceptRA=
This is actually a sysctl value underneath the systemd configuration, in case that makes it easier. net.ipv6.conf.<interface>.accept_ra
