[Android Q&A, Help & Troubleshooting] ase1590:
After recently acquiring and rooting a RK3066 based DoPo td-1010 tablet, I quickly ran out of room for my apps, as I only have 500mb of internal storage. What I want to do now is swap the mounting point of my external SD card with the mounting point of my internal storage.

Listed under settings>storage in ICS are 3 mounted areas:

Internal - 504 mb

NAND Flash - 5.81Gb (I believe this to be a glorified internal SD card)

SD CARD - 7.39 Gb (my external card)

a quick look through vold.fstab reveals that the mount point for Internal appears no to be listed:

## Vold 2.0 Generic fstab
## - San Mehat (san@android.com)
##

#######################
## Regular device mount
##
## Format: dev_mount <label> <mount_point> <part> <sysfs_path1...>
## label - Label for the volume
## mount_point - Where the volume will be mounted
## part - Partition # (1 based), or 'auto' for first usable partition.
## <sysfs_path> - List of sysfs paths to source devices
######################

## Example of a standard sdcard mount for the emulator / Dream
# Mounts the first usable partition of the specified device
#dev_mount sdcard /mnt/sdcard auto /devices/platform/goldfish_mmc.0 /devices/platform/msm_sdcc.2/mmc_host/mmc1
dev_mount flash /mnt/sdcard auto /devices/virtual/mtd/mtd9/mtdblock9
dev_mount sdcard /mnt/external_sd auto /devices/platform/rk29_sdmmc.0/mmc_host/mmc0
dev_mount udisk /mnt/usb_storage auto /devices/platform/usb20_host/usb
## Example of a dual card setup
# dev_mount left_sdcard /sdcard1 auto /devices/platform/goldfish_mmc.0 /devices/platform/msm_sdcc.2/mmc_host/mmc1
# dev_mount right_sdcard /sdcard2 auto /devices/platform/goldfish_mmc.1 /devices/platform/msm_sdcc.3/mmc_host/mmc1

## Example of specifying a specific partition for mounts
# dev_mount sdcard /sdcard 2 /devices/platform/goldfish_mmc.0 /devices/platform/msm_sdcc.2/mmc_host/mmc1

Dev_mount flash links to the NAND Flash partition. this is the area apps which support movement to the SD card are moved to. Again, the Internal storage partition appears on to be listed.

After installing busybox on my tablet, and installing a terminal emulator, an output of cat /proc/mounts reveals this:

As I am unfamiliar with Android mounting points, I am unsure what I am looking for/which partition is the one Internal is using.

Any help?
