  Ahh, yes.  I do have a default setup.  That should be changed/removed.

  (Function 'setupDefaultOptions()' in xen-create-image.)

  Great.

  Yes, the value that is specified as the initrd line is just
 interpolated into the generated file.  If you want it removed you
 must edit the template file /etc/xen-tools/xm.tmpl.

  I could change the template to read:

  { if ( $initrd )
    {
       $OUT .= "ramdisk = '$initrd'\n";
    }
  }

  That would avoid including the line if it wasn't required, but
 I think that would be confusing to read - and overkill if an
 empty value doesn't confuse xm.
