This small set fixes few bugs, improves gpt handling (under buggy conditions) and implements strict flag with more fine grained control which should fix issues with sanity checks against disk sizes. If this set is allright I'd want to do what I mentioned in older discussion with Ady - backport missing patches from 6.x to 5.x and 4.x so all versions have up to date chain version. Michal

This is a bit updated set of chain.c32 changes that simplifies a few things (and in partiter part), fixes few minor issues and adds a few new features. Details are in the following commits, below is the summary and pull details at the end. Shao - any chance to peek over them ? Most of those are relatively simple changes and well tested, though of course something might have slipped my attention.

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
