Bricking is a rather extreme firmware bug, but even if it didn&#x27;t brick itself - if it just lost a bunch of information (Boot list, Vendor information, Time, BIOS settings, Windows activation data &#x2F; preinstalled keys... I don&#x27;t know all the kinds of stuff you can put in there.)... wouldn&#x27;t that also be bad? I would never expect to be able to cause that by deleting a directory. So by the principle of least surprise, this shouldn&#x27;t be mounted by default.<p>So on a non-broken BIOS, there is &quot;technically&quot; no bug - but the pieces (BIOS, Kernel, Systemd) come together to make a bad design.
