Since I tire of seeing people hit this ignorant opinion in the list
archives, I'll just offer the rational counterpoints.
- The MBR partition table is not "obsolete", it's a part of the PC
architecture specification.
- You omit the fact that many peripheral device vendors' BIOS code looks
for the MBR partition table, and will fail if it's not present or
incorrect.
You do realise that "DD" mode does include a (invalid) MBR partition
table (now valid, courtesy of a long-needed fix), right?
I'd love to never hear those invalid, unuseful, misleading opinions from
you again.
