Am I missing something? How can I make using Arch Linux my personality when once it’s set up it’s just like any other computer?
IMO there’s nothing about Arch, or any other distro, that makes it worth using, beyond whatever goals you have. If Arch helps you accomplish that goals, great. If not, pick a different distro that does.
In my case, I want to use the latest version of software and use my own configs without inadvertently breaking stuff, based on some arbitrary set of assumptions that distros like Ubuntu or Fedora have made about how their own distro should be used, and Arch has been the easiest way to do that for me.
