Oof, that quote is the exact brand of nerd bullshit that makes my blood boil. “Sure, it may be horribly designed, complicated, hard to understand, unnecessarily dangerous and / or extremely misleading, but you have nOT rEAd ThE dOCUmeNtATiON, therefore it’s your fault and I’m immune to your criticism”. Except this instance is even worse than that, because the documentation for that command sounds just as innocent as the command itself. But I guess obviously something called “tmpfiles” is responsible for your home folder, how couldn’t you know that?
Mozilla “sold their soul to Google”? What did I miss?
