+- The systemd-networkd `ManageForeignRoutes` and `ManageForeignRoutingPolicyRules` settings are now disabled through a drop-in file and thus can only be enabled again by a drop-in file under `/etc/systemd/networkd.conf.d/` because drop-in files take precedence over `/etc/systemd/networkd.conf` ([PR#61](https://github.com/flatcar-linux/init/pull/61))

-Subject: [PATCH 8/8] networkd: disable managing of foreign routes/rules by
- default
-
-While systemd-networkd follows the principle of a declarative network
-configuration and thus needs a way to ensure that unwanted routes or
-routing policy rules get discarded, the interfacing with procedural
-network management from CNIs like Cilium is limited, so that when the
-interface is set to "unmanaged" through a networkd unit, any routing
-policies there would also be ignored and discarded unless they would
-be defined for a new unit for a dummy network interface. This means
-the only option left is to disable the discarding of foreign rules
-globally.
-
-Change the default for ManageForeignRoutes and
-ManageForeignRoutingPolicyRules to "no" to ensure that we don't
-interfere with the network management of the CNIs. Users that rely on
-the setting can still enable it again. The default networkd config
-mentions the setting with a default value but since the networkd
-config resides on "/etc" it isn't auto updated on Flatcar and users
-may still see a wrong default value annotated there.
