Perry, I just revisited this: - /etc/network/if-up.d/openssh-server hack introduces a race (you run into connection errors after bringing up a new interface as sshd stops listening briefly while being reloaded).
- I can't seem to be able to actually reproduce that issue: I can start a VM with no network interfaces, remove the above hack, then start sshd, then bring up an ethernet interface, and I can connect to ssh via ethernet just fine. Also, e. g. Fedora has no counterpart of this hack, and these days a lot of people would complain if that would cause problems, as hotpluggable/roaming network devices are everywhere. - /etc/network/if-up.d/ isn't being run when using networkd/netplan, thus in our cloud instances. So far this doesn't seem to have caused any issues. So my questions: (1) Can you please describe more precisely what exactly you did back then? Do you have a nonstandard SSH configuration with some ListenAddresses/AddressFamily restrictions or similar? (2) Can you please disable the hack (sudo chmod 0 /etc/network/if-up.d /openssh-server) and check if your use case works without it?

(Yes, some of us really do want to be able to remotely log in to our laptops after we bring them home and they roam onto the home WiFi network etc.) Right now there is no sshd script in /etc/network/* but it would be trivial to create one and add it to the package. For sshd, it would be simplest just to restart the daemon.
