Log Message:
-----------
Fix partitionning on sparc raid1.
We need to skip first cylinder or md partition erase partition and second.b

Suppress the boot flag for sparc as it is not used there
You could boot any partition from obp with boot disk<disk number>:<part number>

Better document the rules to be used for a sun label partitionning
