> 1. That's only if you're still keeping a separate /boot filesystem, for starters. (Why in 2012, by the way? The 1024-logical-cylinder limit on x86 went away ages ago.)
And the 2TiB limit came up to take its place. I'm glad that separate /boot is still so well supported. I have a system with 3 TB drives, but the BIOS only recognizes and boots from MBR partition tables. I need a /boot partition entirely contained within the first 2 TiB, and then a GPT containing the actual partitions for Linux.
