Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   * What was the outcome of this action?


Debian12
openssh-server                  1:9.2p1-2+deb12u5    arm64 

sshd starts before the ethernet interface gets an IP address.

With 
ListenAddress 192.168.0.2
in
/etc/ssh/sshd_config

Result
error: Bind to port 22 failed: Cannot assign requested address.


systemctl edit sshd.service
and inserting the following:

    [Unit]
    After=network-online.target
    
does not help.

   * What outcome did you expect instead?

sshd active after reboot when ListenAddress is set in sshd_config
