Dear Maintainer,

after upgrade to debian 12 from debian 11, the system boots using almost ~2min
to prompt login.

after check for systemd-analyze, get info:

root at vm:~# systemd-analyze time
Startup finished in 2.246s (kernel) + 2min 3.788s (userspace) = 2min 6.035s 
graphical.target reached after 2min 3.610s in userspace.

root at vm:~# systemd-analyze blame
2min 189ms systemd-networkd-wait-online.service
    4.253s kdump-tools.service
    1.910s apparmor.service
    1.267s ifupdown-pre.service
    ...

in my machine there is not using systemd-networked, and no interfaces managed by
networkd.

so i search for it online, and there was an issue in systemd's github:
systemd-networkd-wait-online waits undefinitely if no networkd managed interfaces
https://github.com/systemd/systemd/issues/25813

and fixed in systemd 253, with release note:

      systemd-networkd-wait-online exits successfully when all interfaces
      are ready or unmanaged. Previously, if neither '--any' nor
      '--interface=' options were used, at least one interface had to be in
      configured state. This change allows the case where systemd-networkd
      is enabled, but no interfaces are configured, to be handled
      gracefully. It may occur in particular when a different network
      manager is also enabled and used.

so i try to install systemd 253 from experimental, it fixes the long boot.

please consider patch it to debian 12 bookworm, thanks.
