   is to implement a "bootloader selector".

The default bootloader-installer will be set during build
of the bootloader-selector. The bootloader-selector has a low
debconf priority, so it wouldn't be shown by default.

At menu item number 7200 is the 'isinstallable'-flag set to true
for the installer udeb. With a higher (more detailed) debconf priority
will the user be asked for the bootloader of choice. This is where
grub or grub2 can be selected. A bootparameter has the same effect.
