Glad you are enjoying Arch. I agree, it is no longer hard to install.
Do you have an example of something in the Arch wiki that does not apply to EOS?
I mean, I guess most people self-installing Arch are not choosing Dracut (though you could and the Arch wiki covers it). I cannot really think of anything else though.
Started with Soft Landing Systems (SLS). Pre-Slackware. Many hours downloading floppy disk images at school.
Moved to Red Hat (pre-Fedora and pre-RHEL) until I think 7.3 or so and then Mandrake. I did trial runs with many distros over time but none of them really stuck. Fedora for a release or two. Spent a few years on Manjaro for desktop and CentOS for server. Have been on Arch for many years now (or EndeavourOS). Never used Ubuntu really.
Moved to Proxmox for server. Although I never used Debian historically, quite a few of the containers I have on Proxmox now are Debian based as is Proxmox itself.
Lately, I have been using Chimera Linux for desktop though I have an Arch Distrobox on it so I guess I am a bit of a hybrid at this point.
