In case when rootfs is restored (unpacked) from sstate, we have to clean

Hi, this skips hidden files. Can't we use

rootfs_install_sstate_finalize[root_cleandirs] += "${ROOTFSDIR}"

instead? Then we could also avoid the following mkdir.

Hi, 
I thought about it, but in this case logic will be different, the ROOTFS dir will be deleted always.
But in current implementation it's deleted only if rootfs.tar exists.

> this skips hidden files It will skip hidden files only in root. Is it real case (hidden files in root)? I can change it to 'rm -rf ${ROOTFSDIR}'. Aliaksei

         mkdir -p ${ROOTFSDIR}
         tar -C ${ROOTFSDIR} -xp ${SSTATE_TAR_ATTR_FLAGS} -f rootfs.tar
