[CentOS] What are the differences between systemd and non-systemd Linux distros?
Systemd is implemented in all the major distros, if you want to find ones that don't search for non-systemd.

We had this discussion here years ago when we were staring and the impending transition. Read the archives on the angst the change engendered and the adjustment to the new methodology.

Linux kernel is already containing chunks of code related to systemd/firewalld and friends. One can disable stuff during kernel build, but the result it still is not like the result of building kernel before the existence of systemd/firewalld. Also, it is likely that at some point systemd-free Linux distribution(s) may fade away. That said, if one is strongly willing to stay away from systemd, and not to such extent into Linux as to needing an advise on that, I would recommend to take a look at non-Linux system, specifically BSD descendants (FreeBSD, NetBSD, etc). Their kernel is not as heavy (big,resource demanding) as Linux kernel, and you can do pretty much everything one needs (except maybe computer games, although these will fall mostly into MS Windows scope). I for one have FreeBSD on my laptop (with alternative boot into Debian, the last being systemd though...). I hope, this helps.

It's true that systemd uses some Linux-only features like cgroups, but I was using those features well before systemd came around. And firewalld uses Linux only specific features too -- it manages the NETFILTER rules which is a linux-specific project. The only thing that seems to be in common is that they are both projects that end with 'd'. I suppose you're going to start claiming that SSHd, HTTPd and NTPd are up to no good.> Also, it is likely that at some point > systemd-free Linux distribution(s) may fade away.There was already a move away from SysV init before systemd was introduced, heck RHEL6/CentOS6 used Upstart instead of SysV. There are always going to be projects with a diverse set of tools, it just depends on how many people care about it. Turns out, not that many people care about maintaining a SysV init (or other init) distro. -- Jonathan Billings <billings at negate.org>

But do watch the entire presentation - good stuff.
