Content-Type: text/plain; charset=ISO-8859-1; format=flowed Sender: util-linux-owner@vger.kernel.org List-ID: Hi! I was learning about GPT when I noticed this behavior of fdisk which I never though about before. Regardless of the partition table, fdisk always starts the first partition at 2048. In reality, the maximum size required by the gap between MBR and the 1st partition is a single sector, which's used by GRUB 1.5. GPT doesn't need this space at all. Then extended partitions too have a gap of 2048 sectors. Why this behavior?
