./rules/post/000_ptxd_make_image_definitions.make:12:image/permissions
:= $(IMAGEDIR)/permissions


ultimately the permissions file which I cannot find in the ptxdist directory. 

Actually I am creating a script to generate the root.ubifs separately from environment

-------------------------------------------
LEB_SIZE="126976"
MINIMUM_IO_UNIT_SIZE="2048"
MAX_LEB_COUNT="3929"
EXTRA_ARGS=" -F"
ROOTFS=root.ubifs
FS_SOURCE_PATH=/opt/PHYTEC_BSPs/phyCORE-AM335x-PD13.1.2/platform-phyCORE-AM335x/root
MKFS_UBIFS=/opt/PHYTEC_BSPs/phyCORE-AM335x-PD13.1.2/platform-phyCORE-AM335x/sysroot-host/sbin/mkfs.ubifs

$MKFS_UBIFS -d $FS_SOURCE_PATH -e $LEB_SIZE -m $MINIMUM_IO_UNIT_SIZE -c $MAX_LEB_COUNT $EXTRA_ARGS -o $ROOTFS


----------------------------------------------

I need to add the permission manipulation and trying to figure out how to fit in this script.
