[Replicant] access to storage (was: default rights on storage)

[Fil Lupin]

Hi,
trying to get back the content of my GT-I9100 internal memory, I failed into my attempts to dump sdcard0 and usbdisk0
It was installed with Replicant 4.2 and crashed.
Here are steps I tried:.
```
$ adb pull /devices/platform/dw_mmc/mmc_host/mmc0/mmc0 sdcard0
adb: error: remote object '/devices/platform/dw_mmc/mmc_host/mmc0/mmc0' does not exist
$ adb pull /devices/platform/s3c_otghcd/usb usbdisk0
adb: error: remote object '/devices/platform/s3c_otghcd/usb' does not exist
```

I found into /etc/vold.fstab config lines for mounting partition which seems to use `dev_mount`, but I can't find any binary named dev_mount.

Do you know how I could get access to my sdcard0 and usbdisk0?

Thank you,

- Fil Lupin.

I imagine it could be sufficient to get my data back from sdcard0 and usbdisk0, I just need to understand how to access them. I you have any idea, I'm aware :)
