If you actually want a reason, then most people experience faster boot up times using runit instead of Systemd. I haven't tried it yet though.
maybe if you ran systemd you wouldn't have to boot up so often that actual boot times mattered that much.
I'm curious if there's any quantitative evidence to show this.
There is none. It's all conjecture or circumstantial.
I think it would be pretty easy to qualitatively test this
But then it wouldn't fit the "systemd = devil" narrative if it was actually tested and found out to be false lol
I think it would not actually be easy to test this. The massive combinations of hardware and software configurations in use out in the world make it nearly impossible to conclusively say one way or the other.
For instance consider the hypothetical of a service with a bug that increases its startup in certain circumstances. If Systemd triggered this bug and OpenRC didn't because of some default setting in each, perhaps a timeout setting, would you say OpenRC is conclusively better at start up time? Not really, they just got lucky that their default bypassed someone elses bug. Just off the top of my head other things that would probably cause hell in comparisons are disk access speeds, RAM bottlenecks, network load, CPU and GPU temp and performance etc.
You can perhaps test for specific use cases and sets of services, but I think this is more useful for improving each init system than it is as a comparison between them.
Is boot time that much of an issue besides for arbitrary competitive reasons? I haven’t tried any optimizations and boot time on my headless server is less than two seconds.
It comes in handy for people who wants to run Linux on their notebook without being an engineer and look at Mac users with envy because of their "ready to work" time on their macbooks of 1-2 seconds after they open the lid.
On a server, it solves nothing.
I maybe reboot my computer once a month. Why care?
