+You will probably find it useful to create an account for you in the
+GNU/Hurd virtual machine and to authorize logins with your SSH key.  To
+do that, you can define the GNU/Hurd system in the usual way
+(@pxref{Using the Configuration System}), and then pass that operating
+system as the @code{os} field of @code{hurd-vm-configuration}, as in
+this example:
