Looks about right.

No.

mkpart ext3, xfs, etc. should work properly.  Compaq diagnostic isn't
supported properly, sorry.

0x83 IIRC.  Yes.  Except LVM/Raid, IIRC.

You can put xfs there if you want.  But both will work, right.

I personally think partition types should be abolished.
Linux can-and-does figure out the fs by probing.  It ignores partition
types.  (Except LVM, etc.)
