title: Xen and Linux cannot create directory while root
body: <p>This question is pretty straightforward.  I've googled around and not seen any help.</p>
  
  <pre><code>root@sdna-23 :) #pwd
  /sys/hypervisor
  root@sdna-23 :) #whoami
  root
  root@sdna-23 :) #mkdir test
  mkdir: cannot create directory `test': No such file or directory  
  root@sdna-23 :( #
  </code></pre>
  
  <p>.....Why? I want to copy files into this directory....that won't work either....</p>
