Yes, I am amazed that quite a few people in this thread are saying they ‘had to completely reinstall the os’ and that it broke everything after not much time. As long as one doesn’t rely on the AUR for system critical packages or much in generel, it is incredibly hard to break an Arch system (Manjaro and other Arch-based distros don’t count). This is due in part to Arch being quite reproducible but it also having very good maintainership.
It doesn’t hurt to apply new package configs by going through pacdiff
once in a while though.
Edit: Typo
It’s beyond me why Valve hasn’t yet deleted that page or at least updated it to make it clear that it’s an obsolete version that hasn’t received an update in 8 years.
