I do know that one of systemd's reasons for existence is the ability to
postpone running a daemon (httpd for instance) until a listener asks
for it, thereby eliminating the need to run inetd itself. Although I've
never done it, it looks to me like
http://0pointer.de/blog/projects/inetd.html has a simple example for
instantiating one sshd process per connection, without the need for
inetd, involving both a normal service and a systemd socket.

I don't normally use systemd, but the best resource I've found for
understanding it is https://www.youtube.com/watch?v=S9YmaNuvw5U . The
most productive way to watch that video is to pay exquisite attention
to Ben Breard, while ignoring the ramblings of Lennart Poettering.

If you can't get systemd to be a superserver, would it be possible to
start inetd from systemd, and then just use inetd the same way you've
been using it the past 15 years?
