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.
