[RFC] Add XFS support in SYSLINUX

[CHEN Baozi <baozich@xxxxxxxxx>]

Hi all,

I'm a student applying for this year's GSoC and planning to add XFS support to 
the syslinux bootloader. I did some research on the syslinux's implementation, 
and have a rough idea. 

XFS starts its superblock from the first bytes of partition, where syslinux 
would install its boot codes(in the first 512 bytes). Currently, we have two 
approach to handle that. One is to follow the GRUB that put its codes in the 
first few bytes immediately following the MBR and before the first partition's 
first sector. However, this approach breaks some designing rules of syslinux, 
so it won't be accepted. The other one that we are now considering is to use 
the remaining 2048 bytes left in XFS's first block. But I'm not sure that this 
area is reserved for some new features in the future. 

Any comment?

Regards,
Chen Baozi
