Specifically, how are you handling
different filesystem structures in the boot sector?

On the PC the bootblock (512 bytes) load the GRUB kernel.  This is a
binary image with a maximum size of 32KB (IIRC).  This is loaded from
a fixed location and no filesystem specific code is involved.

I suppose that the consequences of this are that filesystems that don't store the kernel contiguously (ie. compression, small-file consolidation tricks) on disk will be incompatible with GRUB2? Don't get me wrong, I think it's a reasonable tradeoff, I just want to make sure I understand correctly.

BTW, how does one force a filesystem to store a file contiguously on installation of the GRUB kernel?
