As an older timer (on my way but not there yet), I never cared for the init.d startup and I dislike the systemd monolithic architecture. What I do like is Solaris SMF and wish Linux would have adopted a method such as or similar to that. I still think SMF was/is a great comprise to the init.d method or systemd manor. I used SMF professionally, but now I have moved on with Linux professionally as Solaris is, well, dead. I only get to enjoy SMF on my home systems, and savor it. I'm trying to like Linux over all these years, but this systemd thing is a real big road block for me to get enthusiastic. I have a hard time understanding why all the other Linux distros joined hands with Redhat and implemented that thing, systemd. Sigh.
