My thoughts on systemd are complicated but I wasn't around at the time of systemd
Personally it is my opinion that Linux really split in two due to systemd partially because of the idea of the sheer size of systemd code
There are things like https://github.com/Sweets/hummingbird which, I, not even a C person can understand and appreciate its simplicity.
I am not saying that we always need such simplicity, but that I am merely giving an opinion that there are people who actually want to understand what they are running as their root and this sense of "control" really is so hard to get from things like system-d
System-d is also thus a little "bloated" compared to other inits which really show in systems like containers etc. where most developers if possible try to have alpine containers (I have seen this especially so much in golang/rust communities partially because golang is mostly static available and rust can be done the same too or compiled with musl pretty easily)
As such, personally, I can understand both systemd and other init systems, I feel like there are some guides which prefer using hummingbird etc. (https://github.com/comfies/tldrlfs) and I feel like for actually understanding "linux" from linux from scratch, other inits can be good.
Another minor nitpick I have of systemd is that its glibc based, Glibc has some of the weirdest complexities I have ever seen and a lot of package management in my opinion has been built around it and personally it feels like the decisions were made in a different era where different types of resources were constrained and updates weren't as widespread but now it has been a mess which is why we need so many linux distros in the first place with their opinions and package management
I genuinely prefer musl for this, So I prefer things like alpine/void in the process as well yet to me, freedom matters a lot. There should be a freedom of choice in such matters and systemd severely restricts it for many.
I feel like systemd is way too ambitious and which is why it requires glibc to be more feature complete in the first place, not sure if its a good or bad thing but I am merely stating what I feel like.
As I said, I have nothing against systemd myself but I am just giving the nuance I felt like, as I was trying to build my own linux distro trying to make it hyper compact and I came into this rabbit-hole, My philosophy almost was out of curiosity regarding what are the smallest systems which are still functionable (Hint: its tiny core linux which is an absolute pleasure although it isn't "secure" partially because they run everything as root If I remember correctly but )
>We are running systemd with all bells and whistles on Raspberry Pi based 1 GB RAM systems. systemd-networkd, iwd, timers etc. The base usage barely touches 350 MiBs
Okay but what are your thoughts on alpine, Alpine's motto or the first thing you see in bold letters on their website (https://alpinelinux.org/) is
Small. Simple. Secure.
Alpine Linux is a security-oriented, lightweight Linux distribution based on musl libc and busybox.
Combined with either gcompat to run glibc or personally I genuinely prefer golang/rust applications (mostly golang) like running gitea on alpine etc. and I found it to be an absolute pleasure server side to work with mostly, except sometimes software download especially python when I was running alpine on android using userLand was a somewhat-issue but maybe I had skill issue or something but I genuinely learnt a lot trying to install python on it.
Bun/Deno just works out of the box, in fact deno is even available in the apk format of alpine out of the box
I truly love alpine/appreciate its message. I feel like systems should be small partially because that means that such software could run even on much older systems just out of the box
Alpine features raspberry pi images and there is dietpi which has some decent low iso file sizes, Check them out as well if possible
Personally I love alpine but I also love the idea of using debian or some immutable distro which uses systemd and then running alpine in container, it seems to be the best of both worlds really.
