While [Neal's install guide](http://web.walfield.org/papers/hurd-installation-guide/english/hurd-install-guide.html) is very good it does not have complete information regarding the GRUB boot loader. The syntax is also different from Lilo's and so to scratch my own itch I'm creating this quick reference. The [Grub manual](http://www.gnu.org/manual/grub/html_mono/grub.html) is another good reference.

* update-grub is **Debian specific** and very nice. It will automatically create a /boot/grub/menu.lst file for the kernels in /boot/. It will also append a manually configured set for other partitions like the GNU/Hurd.
* grub-floppy is **Debian specific** script to create a boot floppy.
* mkbimage is another boot floppy creation script.
* <http://khazad.dyndns.org/packages/grub-disk/> contains a Debian packaged makefile for creating CD &amp; floppy images.
* essential Grub commands &amp; disk syntax
  * root
  * kernel
  * module
  * boot
* sample file
