Arch is aimed at people who know their shit so they can build their own distro based on how they imagine their distro to be. It is not a good distro for beginners and non power users, no matter how often you try to make your own repository, and how many GUI installers you make for it. There's a good reason why there is no GUI installer in arch (aside from being able to load it into ram). That being that to use Arch, you need to have a basic understanding of the terminal. It is in no way hard to boot arch and type in archinstall. However, if you don't even know how to do that, your experience in whatever distro, no matter how arch based it is or not, will only last until you have a dependency error or some utter and total Arch bullshit® happens on your system and you have to run to the forums because you don't understand how a wiki works.
You want a bleeding edge distro? Use goddamn Opensuse Tumbleweed for all I care, it is on par with arch, and it has none of the arch stuff.
You have this one package that is only available on arch repos? Use goddamn flatpak and stop crying about flatpak being bloated, you probably don't even know what bloat means if you can't set up arch. And no, it dosent run worse. Those 0,0001 seconds don't matter.
You really want arch so you can be cool? Read the goddamn 50 page install guide and set it up, then we'll talk about those arch forks.
(Also, most arch forks that don't use arch repos break the aur, so you don't even have the one thing you want from arch)
That depends on what the beginner's goal is. Arch could very well be a nice beginner distro, as could Gentoo or Slackware or any other "hard" distro if you're determined to learn. My baptism of fire was on Slackware in the 90s (which I'm still on), long before "beginner distros". Trying and failing was a big part of the fun. If you're determined to learn, I don't see any issue with starting with a distro that doesn't hold your hand.
Isn't the lack of dependency management a huge pain on Slackware? I think Gentoo is my forever distro, but I'm very curious about Slackware.
Good to hear that you're slack-curious! :D Gentoo is a fantastic distro, so great choice! I run Gentoo on my second computer. I've always loved it, but Slackware was my first linux experience, so it has special meaning to me. Maybe try Slackware in a VM? You'll be compiling a lot from source on Slackware too if you need stuff that's not included in the base system, but without portage for deps management it's a lot more cumbersome. You can of course use sboui, slpkg or some other tool that can manage deps, or use flatpaks, appimages, distrobox or whatever to keep your base system clean.
That does sound like a bit much for my daily driver; I'll have to check it out in a VM sometime. It warms my heart that a distro community can have such longevity, and I think the simplicity has to be a big part of that.
