[Q] GT-P7320T custom rom creation with rom kitchen - Android Q&A, Help & Troubleshooting

Hi guys,
After years of using this site to read up on how-tos for my g1 and desire hd, I have finally hit a brick wall and need to post a question.
My mum won this GT-P7320T branded to telstra ( Australia) and overall, the hardware specs werent too bad, but before the ics update came out finally in january it was terribe to use.
The update has actually been a massive improvement, but being branded and all that junk is as annoying as hell, so i have decided to build my own rom. this is my first time building a rom. ive flashed plenty, but its a different kettle of fish.
i am using the telstra branded stock ics rom with rom kitchen to try to build something acceptable, but first things first, the compiled rom must boot.
because the device isnt supported i have to create i file in the /directory_to_kitchen/tools/edify_defs named GT-P7320T defining all the mount points.
this is where it gets tricky,
here is the contents of the /directory_to_kitchen/tools/edify_defs named GT-P7320T that i have created
#
# The values below should be set in each file in this folder.
#
# Each file represents a device name (set in ro.product.device of
# build.prop)
#
# If yes, then this device requires changing the mount point
# names in the new updater-script or update-script
# DO NOT SET TO 'yes' IF DEVICE IS BY DELL
change_mnt=yes
# If yes, the device is by Dell and requires changing the mount
# point names in the new updater-script or update-script
change_mnt_dell=no
#
# NOTE: The update-script will be converted to updater-script if the
# definition file for the device exists. If 'change_mnt' or
# 'change_mnt_dell' are set to 'yes' then the mount names will
# also be changed.
#
# Mention the mount point names if change_mnt=yes
# Use '\/' instead of '/'
# e.g. sys_mnt=\/dev\/block\/mcblk0p25
#extract from recovery.fstab
#/boot emmc /dev/block/mmcblk0p8
#/efs ext4 /dev/block/mmcblk0p21
#/cache ext4 /dev/block/mmcblk0p25
#/data ext4 /dev/block/mmcblk0p26 length=-16384
#/misc mtd misc
#/recovery emmc /dev/block/mmcblk0p22
#/sdcard vfat /dev/block/mmcblk0p28 /dev/block/mmcblk0
#/system ext4 /dev/block/mmcblk0p24
#
# If unknown, set to: ???
sys_mnt=\/dev\/block\/mmcblk0p24
cache_mnt=\/dev\/block\/mmcblk0p25
boot_mnt=\/dev\/block\/mmcblk0p8
data_mnt=\/dev\/block\/mmcblk0p26 #length=-16384
sdcard_mnt=\/dev\/block\/mmcblk0p28 #\/dev\/block\/mmcblk0
# Set this mount point for the modem.bin in Samsung devices like the Galaxy S2
modem_mnt=
# Set this mount point for the preload partition on some Samsung devices like the Galaxy S2
preload_mnt=
# Set this mount point if you know what it is (e.g. on Motorola Atrix)
webtop_mnt=
# Filesystem info for SYSTEM/DATA/CACHE/etc.
# e.g. param1=ext3, param2=EMMC
param1=ext4
param2=EMMC
# If SDCARD filesystem is different from above, then mention it
# e.g. param1_sdcard=vfat, param2_sdcard=MTD
param1_sdcard=vfat
param2_sdcard=
# If CACHE filesystem is different from above, then mention it
param1_cache=
param2_cache=
# If yes, the device does not require using a 'tmp' folder when
# flashing the boot.img in the updater-script
#
# e.g. package_extract_file("boot.img", "/dev/block/blah1");
fix_boot=no
# If yes, the device requires a 'tmp' folder when flashing the
# boot.img in the updater-script, PLUS the boot partition name
# needs to be used, rather than just 'boot'
#
# e.g. Replace: write_raw_image("/tmp/boot.img", "boot")
# with: write_raw_image("/tmp/boot.img", "/dev/block/blah1")
fix_boot2=no
# If yes, the device requires a 'dd' command to write the boot.img
#
# e.g. Replace: write_raw_image("/tmp/boot.img", "boot")
# with: run_program("/sbin/busybox", "dd", "if=/tmp/boot.img", "of=/dev/block/blah")
fix_boot3=no
# Device uses /cache instead of /tmp, e.g. when writing boot.img
use_cache_not_tmp=no
as you can see,
i have copied and pasted the contets of my recovery.fstab and commented it out as a reference.
this should be quite straight foward, but the mount points for data and sdcard hve additional parameters, which i dont know what to do with.
the parameters are currently commented out and i cannot get it to flash i've tried lots of different combinations but to no avail.
During flashing attempts it is giving me error 7, which to me seems to indicate a problem with setting the mount points.
could sombody please at least point me in the right direction? there is only one other custom rom for this device and i personally don't like it.
many thanks in advnce and i hope i have posted this in the right spot. im all new to this posting stuff and i cant post in any development forums yet

all good i sussed it. it just didnt like a few comments for some reason. ended up writing it by hand.
i am an engineering student and i would really like to look into this rom development a little further.
im thinking of porting cyanogenmod to it, would it be do-able? or is there a reason it hasnt been ported to it before?
