So how does the installer deal with files that are installed in say &#x2F;usr&#x2F;bin that should not be there? Does it leave them there or does it move them? Does it put &quot;rootless&quot; attribute on them?<p>Can you turn off rootless during installation or is this post installation thing only?<p>Does rsync backup continue to work with rootless? I have a feeling that booting from external partition and restoring from backup won&#x27;t work for system files with rootless attribute on them.
