3 OS-specific notes about grub tools
************************************

On OS which have device nodes similar to Unix-like OS GRUB tools use the
OS name.  E.g.  for GNU/Linux:

     # grub-install /dev/sda

   On AROS we use another syntax.  For volumes:

     //:<volume name>

   E.g.

     //:DH0

   For disks we use syntax:
     //:<driver name>/unit/flags

   E.g.

     # grub-install //:ata.device/0/0

   On Windows we use UNC path.  For volumes it's typically

     \\?\Volume{<GUID>}
     \\?\<drive letter>:

   E.g.

     \\?\Volume{17f34d50-cf64-4b02-800e-51d79c3aa2ff}
     \\?\C:

   For disks it's

     \\?\PhysicalDrive<number>

   E.g.

     # grub-install \\?\PhysicalDrive0

   Beware that you may need to further escape the backslashes depending
on your shell.

   When compiled with cygwin support then cygwin drive names are
automatically when needed.  E.g.

     # grub-install /dev/sda
