Does the Yocto rootfs image size is based on real contents included in
When I build the image with very large size of applications and
libraries such as boost, I have my image-rootfs.tr.gz about 44 MB,
then I removed all large size of applications and libraries, I changed
IMAGE_ROOTFS_SIZE to a small size IMAGE_ROOTFS_SIZE = 20000, I thought
the image-rootfs.tar.gz should be reduced to a small size, but it is
still 43 MB I don't believe it is that big, which variable I should
use to reduce the image size?
