I have seen so many times that systemd is insecure, bloated, etc. So i wonder ¿does it worth to switch to another init system?
It used to be that everything in Linux was a file, ideally a text file
Yes? The entire Systemd configuration is done with files. With a very well defined structure called units that you can use to configure, boot, service startup, networking, containers, mount stuff, open sockets… that’s exactly the point Systemd provides a cohesive configuration file format for a system.
Yeah but I’ve interacted with it a lot and most of my interaction is commands sent through one of their programs. Versus scripts like init.d whose contents I can easily inspect and modify. Init scripts aren’t config files, they’re directly executable code.
