I will give one example. Lennart says come on who connects to sshd more than once a month. I can't believe he's never seen a sshd log with constant pass attempts even though passwords are disabled.
You are misunderstanding the sshd example.
How? Systemds method would seem more problematic and wasteful to me if you get connections to it a lot. Home connections even get many ssh connection attempts and in any case it would seem to show he has no experience in administration. -- _______________________________________________________________________ 'Write programs that do one thing and do it well.
