The IMAGE_ROOTFS_SIZE variable is cleaned from the environment.

Variables which can be set from the shell at invocation are defined in
BB_ENV_WHITELIST and BB_ENV_EXTRAWHITE.

Does something like:

BB_ENV_EXTRAWHITE="IMAGE_ROOTFS_SIZE $BB_ENV_EXTRAWHITE"
IMAGE_ROOTFS_SIZE_ext3=512000 bitbake core-image-sato

do what you want?
