Default Need help moving 'Data Storage' to 'External SD' for final part of my rom

Hi

Im building a new 4.2.2 rom for my daughters allwinner a20. The stock one is rubbish and lacking in space. Im on the final part now and ive pumped up the stock roms Antutu score from 6000 to 12000. All running nicely except the lack of space. I need to move the 'sdcard' to 'extsd'.

Ive tried swapping the labels in vold.fstab, no joy. Tried modding the init.rc. no luck. I managed to do it on the stock rom before i started messing around with it and now im not sure what ive done.

Can anyone point me in the direction of any other files that deal with mount points/symlinks that I may have overlooked?

Any help would be greatly appreciated

Chris
