+Subject: Support systemd socket activation
+
+Unlike inetd socket activation, with systemd socket activation the
+supervisor passes the listened-on socket to the child process and lets
+the child process handle the accept().  This lets us do delayed start
+of the sshd daemon without becoming incompatible with config options
+like ClientAliveCountMax.
