During the creation of a disk image (e.g. for a VM), there is the need to create, setup, configure and afterwards detach some kind of storage where the newly installed OS can be copied to or directly installed in. This patch implements partitioning handling. Change-Id: I0ca6a4ae3a2684d473b44e5f332ee4225ee30f8c Signed-off-by: Andreas Florath <andreas@florath.net>
