* gnu/packages/grub.scm (<menu-entry>): New record type. (grub-configuration-file): New procedure. * gnu/system/vm.scm (qemu-image): Remove parameters 'linux', 'linux-arguments', and 'initrd'. Add 'grub-configuration' parameter. Honor them, and remove grub.cfg generation code accordingly. (example2): Use `grub-configuration-file', and adjust accordingly.

(description
|

"GNU GRUB is a Multiboot boot loader. It was derived from GRUB, GRand
|
||
Unified Bootloader, which was originally designed and implemented by Erich
|
||
Stefan Boleyn.
|
||
|
||
Briefly, the boot loader is the first software program that runs when a
|
||
computer starts. It is responsible for loading and transferring control to
|
||
the operating system kernel software (such as the Hurd or the Linux). The
|
||
kernel, in turn, initializes the rest of the operating system (e.g., GNU).")
