It&amp;#x27;s entirely possible to have the user&amp;#x27;s home &lt;i&gt;not&lt;/i&gt; owned by themselves; you might want to do this for example if you have a restricted user who you don&amp;#x27;t want messing around with their dotfiles.</text><parent_chain></parent_chain></comment><story><title>Casually removing root files</title><url>https://ervinb.github.io/2017/08/16/casually-removing-root-files/</url></story>
