[Bug 2098183] Re: Preserve IPv6 configurations when `KeepConfiguration=dhcp-on-stop` is set
I agree to not pursue oracular further in this case.
$ remove-package -m "Superseeded by security, decided to not purse further. See https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/2098183/comments/24"; -s oracular-proposed -e 256.5-2ubuntu3.2 systemd

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

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`

<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.
