wic: Use overhead factor when creating partitions from rootfs directories
When creating partitions sized to given rootfs directories, filesystem creation could fail in cases where the calculated target partition size was too small to contain the filesystem created using mkfs. This occurred in particular when creating partitions to contain very large filesystems such as those containing sdk image artifacts. This same limition is present in the oe-core image creation classes, which can be readily see by changing IMAGE_OVERHEAD_FACTOR from the default 1.3 to 1.0 and building a sato-sdk image. It should be possible to calculate required sizes exactly given the source rootfs and target filesystem types, but for now, to address the specific problem users are hitting in such situations, we'll just do exactly what oe-core does and define and use an IMAGE_OVERHEAD_FACTOR or 1.3 in those cases. Fixes [YOCTO #6863]. Signed-off-by: Tom Zanussi <tom.zanussi@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
