As per ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/v2.18/v2.18-ReleaseNotes : fdisk(8): - supports new command line option "-c" to switch off DOS mode - uses 1MiB offset for the first partition (all these changes are already in the release 2.17.2) I presume the 1MiB offset is to accomodate for grub2. sfdisk would need to be updated to do so too. My attempts in partitioning a drive with a 1MiB post-MBR gap failed with the following command line call: sfdisk -uM -L /dev/sda <<-EOF 1,256,fd ,512,fd ,,fd ; EOF Obviously, this might be due to a bug in sfdisk (ignores the first parameter I set, I've tried with other figures with no success), or my misunderstanding of sfdisk's usage. In any case, sfdisk needs to be modified to accommodate for grub2.
