* export-noobs/prerun.sh: Use nested mountpoint While it seems elegant and intuitive to use separate bootfs and rootfs mountpoints for compressing the partitions, doing so violates a precondition of unmount_image that they be mounted as a tree. This causes the image to not be properly unmounted and detached. A better solution might be to pack up the previous stage's chroot directory, but that rework can wait for the time being. scripts/common.sh: Output device name correctly A misplaced ) in unmount_image caused the loop device to be incorrectly identified, resulting in a fair bit of chaos trying to unmount other filesystems on /dev/mapper devices. Such as / on a LUKS-encrypted installation, for example. The unmount will fail as it should and build.sh will abort the build without any cleanup. Best to avoid that. These changes close RPi-Distro/pi-gen#19
