And that is why my servers run FreeBSD. But when I switched from Fedora to CentOS (quite a while back), it made noticeable difference.

Some of them are like “sliding release”, like Fedora, Debian… And with those you often get surprises just upon routine update something breaks, as package is replaced with higher version which has different internals. But these are a charm to “upgrade” to next release. One can also mention FreeBSD and MacOS as being close to this, IMHO. Others are “Enterprise” very long life. They are being patched by back porting fixes (very effort consuming), but they mostly “unchanged” packages internal wise, so during 10 years of such system’s life cycle, it is only rarely you may have things broken. But when it comes to life cycle end, you effectively have to build new system, as virtually neither of software packages can just step up from release 10years old to todays. You effectively do at once all you did for 10 years of "sliding release” system. Examples of this style are: RedHat Enterprise, CentOS (“binary replica” of the former). With all bad one can say about Microsoft, I would mention MS Windows system on which something you install when it release, will still work when the system maintenance ends 10 years later. So, it is one’s choice, which style of system to install and maintain. I for one chose CentOS for number crunchers and workstations, which takes less of my time to maintain (but FreeBSD for servers, but that is different story). Your choice appears to be different, and we both are right in our choices based of our goals. > But then, there are now things in Fedora that make we wonder if I should switch to > arch.

I can do that with crond, but not with systemd. Systemd has resembling portion of code in mainstream Linux kernel (I bet experts will correct me where I’m wrong). You can try to go with systemd-free Linux distro like devuan (fork of Debian that happened when Debian went systemd way). Or you can try one of BSD descendants, which being such are closer to original UNIX philosophy: FreeBSD, NetBSD, OpenBSD (and variety of others standing quite close to these, or slightly more apart, your duckduckgo search will be as good as mine).
