* Added Docker support - replaced necessity for devicemapper (through kpartx) by using parted and losetup with offsets - added Dockerfile - added dependency for parted and grep - added hints to README.md - common: loop through unmounts, fix shellcheck warnings * stage2: use debconf instead of console-setup patch. Fixes #41
