Well I for one am glad of the systemd init system inside of my Linux
operating system. I would far rather deal with service ini files than
long arcane bash scripts that often re-implement (poorly) things like
pid files, and attempts to prevent more than one instance from running.
You were the one that posted earlier today about the many perils of
programming complicated scripts in bash. Init scripts pretty much hit on
all of those gotchas! It boggles my mind that people would actually
argue in favor of maintaining such things (and yes I have done it on
many servers over the years and it was always a pain to deal with custom
I don't use very many of the systemd modules (most are not even
installed on my machine), nor will I ever need them. In fact I still
have rsyslog running.
