I installed Arch from scratch. Honestly, other than a couple of minor "squirrel catchers" associated with disk formatting it isn't that big of a deal. You don't have to be a graybeard monk to use Linux - Omarchy or not.

What don't you like about Omarchy? I'm not young and I used Fedora before Omarchy. I think it's excellent

What makes it for very young men?

For what its worth, I am part of the very young men you mention* (currently 18) and I have talked to people my age on discord who use Linux.

My opinion is that I think that cachyos is a much more suitable option over omarchy.

Personally out of so many of the distros that I have tried including Omarchy, I found Cachyos to be somewhat perfectly balanced (atleast for me).

So I highly recommend Cachyos if you haven't already!

(On a side note: Fedora is something that I wish to try a bit more as well to be honest and for servers, I mostly use debian/ubuntu or alpine)
