[syslinux] [PULL 0/8] MultiFS suppport for BIOS and EFI

[Paulo Alcantara]

So last week I was wondering if XFS was still working -- even with its
last on-disk structure changes -- and it _suprisingly_ worked as
expected. Right, now I can finally get rid of GRUB and use Syslinux to
boot my Linux on EFI from a rootfs with xfs. Shit, I have two
partitions (the first one being the required ESP) so there is no way to
access the other partitions since because Syslinux does not support
multiple disk and/or partitions -- yet.

I completly refused to accept that and then looked at the current status
of MultiFS support; its original implementation only worked on BIOS.
Therefore I started working on EFI support and -- luckily enough -- I
also had Raphael to help me with development and testing.

(I'm really glad to hack Syslinux again. What a great project...)

The MultiFS syntax is basically "(hdX,Y)/path/to/file", where X is disk
number and Y is partition number.

Please test it and report to us if any issue found.
