[Parted-maintainers] Bug#441033: msftres (parted does not undestand GPT/MBR hybrid)

[Osamu Aoki]

Hi,

I looked into msftres issue.  I was a bit confused.  Now that I realize
OP was talking about flag: msftres.  In my case it is not set.  I can
set/reset it with type command.  So I see no issue.

As for my memo on Type reported by gptsync (based on Partition type
GUIDs), it seems wikipedia description is confusing.  Linux ext2
partition with this partition type set to EFI System (FAT) works best
with gptsync.  If I set this GUID to Linux Data partition GUID: 
   EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
using hex editor then gptsync did not like it.  So this choice of GUID
value of  EFI System (FAT) = C12A7328-F81F-11D2-BA4B-00A0C93EC93B must
be intentional one.  (It is somewhat uneasy but it works.)

In conclusion, problem on MacBook (Intel Mac) is handling of hybrid
MBR/GPT.  Thus inclusion of gptsync code and not zapping initial
444bytes are the key here.
