 From the 2.26 release notes:
  This version provides a completely new sfdisk(8) command; the new version is
  based on libfdisk. If your use cases depend on sfdisk(8), then it is strongly
  recommended to be careful and re-test your scripts. The new version supports
  MBR and GPT disk labels (SGI and SUN are also supported but not well tested).
  The new version no longer supports some obscure MBR-specific command-line
  options nor legacy CHS addressing.

What this means is that any script (there are a ton of them out there)
that tries to create a label for a disk device using Cylinder-Head-Sectors
style will have to be rewritten as the new sfdisk only does sector unit
addressing.
