I'm not very familiar with this topic.
Nor am i familiar with the related topic of block boundary sizes and
Although tpowa tried to explain to me, this is what I wrote down:

* don't use sfdisk or cfdisk, they don't support 1MB bootsectors (which
  is a new standard for 4k sector drives, better alignment and win7)
* parted and fdisk do.
* mbr is soon dead
* https://ata.wiki.kernel.org/index.php/ATA_4_KiB_sector_issues 
* parted is also good for GPT and uefi usage
* fdisk does not support GPT
* but parted has no (ncurses) UI

so yeah, lets figure out if this info is still up to date, and how we
should proceed. it looks like we shoud just use parted, if we can
find/make an ncurses frontend for it, all problems should be magically
