Loopback File -- How to determine the size

   Choose how large to make this filesystem.

   You must create it to be large enough to hold the
   installation itself, as well have enough space to
   save files and write data to.

   General Size Guidelines:

     * A typical workstation installation will be
       900MB or more.
     * A typical server installation will be 1.7GB or
       more.
     * A typical custom installation (choosing
       everything) will be 1.7GB or more.
