[Bug 2081325] [NEW] Oracular: systemd override file not applied due to systemd unit rename cloud-init.service renamed to cloud-init-network.service in cloud-init v. 24.3.1

[Chad Smith]

Public bug reported:

I Oracular 24.10, cloud-init 24.3.1 renamed cloud-init.service to cloud-
init-network.service as part of the single-process mode support.  This
is only introduced in Oracular and not applicable to any stable releases
before Oracular.[1]

livecd-rootfs provides complete override for the entire cloud-
init.service in /etc/systemd/system/cloud-init.service to reorder the
service After=NetworkManager.service NetworkManager-wait-online.service
and drop # Before=sysinit.target. This overridden file is completely
ignored in Desktop Oracular images dated 20240916 because the systemd
unit name cloud-init.service doesn't match the new cloud-init-
network.service name. This results in incorrect systemd ordering that
may impact cloud-init's ability to download configuration when kernel
commandline options provide a nocloud seed url that requires DNS
resolution via a kernel commandline
'ds=nocloud;s=http://myresolvablehostname/'.


To fix this issue, livecd-rootfs should be emitting and override file to /etc/systemd/system/cloud-init-network.service with the latest content provided by cloud-init 24.3.1 in oracular.

** Affects: livecd-rootfs (Ubuntu)
