Personally, I think the idea that you can’t ask the right questions because you haven’t installed Arch manually is a silly notion that’s borderline gatekeeping. It’s why Arch users have the reputation that they do and why Arch itself has a reputation for being difficult even though it really isn’t.
Over the years, I’ve moved from Manjaro to Antergos to Endeavor, and then finally the official archinstall tool. I probably will never be arsed to install Arch by hand, but it doesn’t mean that when something breaks I don’t know how to consult the Arch Wiki and fix it myself.
Do users of other distros not know how to ask the right questions? Are Arch users the only ones who know their system inside and out? I don’t think so. Every person has their own threshold for how much investment they want to make into learning about their system, no matter the distro.
