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.
Summary of the more important changes:
- partiter simplifications and updates
Following brief off-list discussion - this simplifies overkill generalizations,
so the code should be easier to follow and modify.
- add relax flag
Relax option tones down sanity checks which can help with broken layouts and
disk sizes reported differently between machines
- tolerate and handle hybrid GPT+MBR layouts, add prefmbr flag
This recognizes disks with both layouts at the same time, and introduces
'prefmbr' flag to force the use of MBR layout in case GPT is present.
- recognize exFAT
This makes chain exFAT aware by adding yet another "BPB" variation with the
usual stuff (partition offset - now 64bit, drive).
- com32/chain: manglepe_fixchs() correction
Previously fixchs also included start/length 0/0 entries (holes), so this patch
makes it a bit more careful.
- use disk_guid for part_guid for 0th partition (under GPT layouts)
- partiter: make sure 'index' is (-1) also for empty primary partitions
The following changes since commit 7307d60063ee4303da4de45f9d984fdc8df92146:
