"Why do you _NOT WANT SYSTEMD_ out of interest? It's an elegant system"
It is precisely because it is _not_ an elegant system that I don't use it on my Debian systems. It pokes its nose into all kinds of things it shouldn't. It makes non-standard setups unnecessarily difficult. It facilitates wide-ranging attack exploits by enforcing uniformity everywhere. It makes low level troubleshooting more difficult. Each new version exhibits unpredictable behaviour which makes it risky to use on a remote system. Need I go on?
To be fair, you could describe the unit file configuration system on its own as elegant, but the additional feature creep and complexity rule it out for me.
I had actually dismissed Devuan, but I'm pleased to see they've reached this stage.
