Title:
  Preserve IPv6 configurations when `KeepConfiguration=dhcp-on-stop` is
  set

Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Focal:
  Won't Fix
Status in systemd source package in Jammy:

Status in systemd source package in Noble:
  Fix Committed

Status in systemd source package in Plucky:

Bug description:
  [Impact]
  The IPv6 configuration is being cleared even though `KeepConfiguration` is set to `yes`, causing the iSCSI backend system to hang during shutdown.

  [Fix]
  Systemd upstream has addressed this issue.
  https://github.com/systemd/systemd/pull/34989

  [Test Plan]
  <Verify the functionality of KeepConfiguration in preserving IPv6 configurations>
  1. Set up a machine with an iSCSI backend in an IPv6-only environment.
  2. Configure the `KeepConfiguration` option for each network device individually using drop-in configuration files (e.g., `/etc/systemd/network/*.network.d/*.conf`) or set the `"critical"` option to `true` in the Netplan configuration.
  3. Power off the machine and verify that the system does not hang.

  <Verify the serialization and deserialization functionality in the systemd-networkd service>
  1. Enable debugging for systemd-networkd
  > mkdir -p /etc/systemd/system/systemd-networkd.service.d/
  > vim /etc/systemd/system/systemd-networkd.service.d/10-debug.conf
  ===
  [Service]
  Environment=SYSTEMD_LOG_LEVEL=debug
  ===
  systemctl daemon-reload
  2. Restart the systemd-networkd service twice using the `systemctl restart systemd-networkd` command.
  3. Confirm that serialization and deserialization are functioning correctly by checking `/var/log/syslog`

  2025-03-13T00:35:01.596662+00:00 oracular systemd-networkd[3029]: Deserialization completed.

  <Verify that the IP address is removed when KeepConfiguration=no is set>
  1. Check the name of the current network configuration file:
  > ls /run/systemd/network/
  10-netplan-enp0s9.link 10-netplan-enp0s9.network
  2. Create a drop-in directory and override the KeepConfiguration setting:
  > mkdir -p /etc/systemd/network/10-netplan-enp0s9.network.d
  > vim /etc/systemd/network/10-netplan-enp0s9.network.d/10-netplan-enp0s9.network.conf
  ===
  [Network]
  KeepConfiguration=no
  ===
  3. Restart the systemd-networkd service to apply the changes:
  > systemctl restart systemd-networkd
  4. Stop the systemd-networkd service and verify the IP address is dropped:
  > systemctl stop systemd-networkd
  > ip a

  [Where problems could occur]
  The patches introduce network serialization and deserialization behavior, ensuring that DHCPv6 addresses are preserved when `KeepConfiguration=yes` is set. If any regressions occur, error messages may appear when restarting `systemd-networkd`, but they will be ignored. Both IPv4/IPv6 configuration and the IPv6 connection may be affected.
