Who thinks that Arch always broke is one of the two:
- An user that is trying to mess with the system always; or
- A person that don't know Arch and is repeating non-sense
My Arch install has almost 5 years and I never had an issue that was like "oh no! O need to reinstall everything!"
Interesting enough, when I was using release-based distros, almost every big update my system become unstable and I had to reinstall me whole system.
