GNU cat

You mean GNU cat?

I like FreeBSD, OpenBSD, Alpine, and Devuan.

Nintendo 3DS

Neither Haiku or 9front use systemd, and they're both very interesting from a technical and design perspective (though not for their init systems).

If it has to be a Linux distribution I would say Damn Small Linux (DSL), because its really impressive just how few resources it requires. You can run x windows and even browse the web (using Dillo) on a system that's small enough to fit in the L3 cache of some modern CPUs.

I don't daily drive any of these though, so they might not count as my "favorite".

systemd is great

what is that little pixel cat at the top? It also appears on https://katia.ripe.net/ is it referencing something?

PalmOS. So simplistic yet powerful. I miss those old PDAs :(

Alpine Linux would be my favourite, although I only use it as a server distro. I use Artix as my daily driver for personal computers because of the AUR and glibc (Alpine is musl). I also enjoy Void but it's not got as much software as Artix repos + AUR.

OpenWRT

Windows 7

Debian that i haven't updated in 10 years

In terms of Linux, either Devuan sysvinit, Void, or Alpine.

I am also a fan of BSD.

FreeBSD! It's so simple, and so reliable

GNU Guix System, using GNU Shepherd as init. It does its job quite well.

postmarketOS, though they are in the process of migrating to systemd. Not that I personally mind terribly much, even if it feels like a bit of an odd choice. So maybe I should say Alpine.

I have to write startup scripts time-to-time and I have to say that I don’t miss at all the old init-system.

Not that systemd don’t have flaws, but in old init-system even simplest daemon took too many lines. Not to mention hacky comment definitions.

OpenBSD

Artix is an under-appreciated gem.
