When using an init system with Linux, you are most likely going to be using Systemd. Systemd is what comes with the majority of Linux distros as of current. However, there has been a lot of criticism against Systemd. Luckily, there are other init systems that you can use. I am going to provide some of the alternatives, and you can decide for yourself what you would like to use as a init system.
Politically i dislike systemd, it just gives Red Hat too much control over GNU/Linux.
But functionally, systemd is an amazing… linux framework, let’s say, and as an operative system that rules over the supercomputer market and the server market, you need that. GNU/Linux has to be the most advanced operative system on earth since it operates on the most advanced fields. So it’s just natural that Red Hat wanted such thing.
Have you tried OpenVMS? Just saying…
