This looks like a MBR partitiontype (both the length and the concept of
extended partition seem MBR-related) - Do we want to support MBR disks?
(we do not in the installer and when initializing a new disk)
Any pointer to where this could be needed?

Really meant as an expression of my confusion - am fine if we want to
support this and the patch LGTM.
