Bug#997006: closed by Debian FTP Masters <ftpmaster at ftp-master.debian.org> (reply to Michael Biebl <biebl at debian.org>) (Bug#997006: fixed in systemd 247.3-7)

[Linus Lüssing]

Just tried 247.3-7 and it fixes the LXD systemd-networkd issue for
me. Thanks a lot for your great maintenance work, will forward the
good news to the LXD forum once it propagates from
stable-proposed-updates to stable. I'm sure a lot of people there
will be happy about this, too.

Regards, Linus
