They can't mesh other than by convention.  When updating the config, 
kernel, initrd, etc., files you are working with the OS (doesn't have to 
be linux) view of the filesystem and it's relative locations.  When grub 
boots, it only has the bios view of things and only sees one partition 
through the bios conventions.
