  This hook shrinks your initramdisk to a smaller size 
  by autodetecting your needed modules. 
  Please take a look at the included modules for completeness,
  else your system might be unbootable.
  Valid Hooks are: base,udev,ide,scsi,sata,usb,fw,filesystems
  Put this hook at the end of your valid hooks. 
  Put other hooks behind autodetect hook.
