 Features:
 
+* Teach systemd-ssh-generator to generated an /run/issue.d/ drop-in telling
+  users how to connect to the system via the AF_VSOCK, as per:
+  https://github.com/systemd/systemd/issues/35071#issuecomment-2462803142
+
 * maybe introduce an OSC sequence that signals when we ask for a password, so
   that terminal emulators can maybe connect a password manager or so, and
   highlight things specially.
