Bug#992038: systemd: regression with systemd-networkd + dropbear initramfs and kernel ip autoconfig(?)

[Axel Scheepers]

Hi Michael,

v249 works fine so far :)

I think the issue is handled in this bugfix from systemd:
https://github.com/ssahani/systemd/commit/7f676aa324cb5498a5f9caaaa3d51ecfe53242e0
https://github.com/systemd/systemd/pull/6918

It was my understanding this was in 247 but it's not. I've build a local
package with this patch included, will see if that works. v249 is quite
different in this area.

Fwiw, the machines are connected to a Fritz!Box 5490 router/access point
and has ipv6 prefix delegation configured (but this is not used for the
clients).

Kind regards,

Axel Scheepers
