properties - Allow to mount the Android resources
properties - Edit the mount points list

$ANDROID_ROOT
/cache
$ANDROID_DATA
/su
$ANDROID_STORAGE/emulated
$ANDROID_STORAGE/4D47-9860

this result in

ubuntu@localhost:~$ df -a

ubuntu@localhost:~$

on android 4.2.2 the paths differ

$ANDROID_ROOT
/cache
$ANDROID_DATA
$EXTERNAL_STORAGE
$SECONDARY_STORAGE

this will bind mount all android partitions into linux chroot container
(the latter one is your external MicroSD card)

/system
/cache
/data
/storage/sdcard0
/storage/sdcard1
