NAME

Boot::Grub - Grub bootloader configuration module.

  my $bootloader = new Boot::Grub(%bootvars);

  if($bootloader->footprint_loader()) {
      $bootloader->install_config();
  }

  if($bootloader->footprint_config() && $bootloader->footprint_loader()) {
    $boot->install_loader();
  }

  my @fileschanged = $bootloader->files();

The following methods exist in this module:

files(): The files() method is merely an accessor method for the all files touched by the instance during its run.

footprint_loader(): This method returns "TRUE" if executable Grub bootloader is installed.

footprint_config(): This method returns "TRUE" if Grub's configuration file, i.e. "/boot/grub/menu.lst", exists.

dev2bios(): This method is used as an internal method. It takes a path to the device as the argument and returns device syntax ( matching an entry in the device map file) used by Grub

install_loader()

install_loader() is an internal method.

This method invokes the Grub executable. Grub write the boot image onto the MBR of the bootable disk.

getdevhash()

getdevhash() is an internal method.

This method takes full path to a file on disk as input, and breaks it down into Grub readable device name and the remaining part.

install_config(): This method read the System Configurator's config file and creates Grub's menu file, i.e. "/boot/grub/menu.lst".

setup_kernel(): An internal method. This method sets up a kernel image as specified in the config file.
