Hm, that's interesting: now i have this problem too. I never had it, when using my own mountpoint (/mnt/sdcard2). Just tried it again with own mountpoint and the problem is gone again...
are there important reasons not to use an own mountpoint?

Then I did a new install of the android support. After that the /data/sdcard folder was *completly* empty. The android support deleted the hole folder, I think. I had some pictures before uninstalling and installing the androis support in that folder, but everything was gone, not only the folders of the android apps. If someone binds the root of the sdcard to /data/sdcard, do not uninstall and install android support, before you have a backup.

that's good to know!

Edit: it totally seems like the mount-sd.sh is called twice during bootup process.
One time at an early stage, where the ambiance stuff works (but default mountpoint is not ready).
And one time later, where the default mountpoint is ready, but it's too late for the ambiance stuff.

When i add these lines at the end of the file

Code:

if [ "$ACTION" = "add" ]; then
    mount /dev/mmcblk1p1 /mnt/sdcard2
    mount -o bind /mnt/sdcard2/.home /home/nemo
    mount -o bind /mnt/sdcard2/.android /data/sdcard
else
  umount /data/sdcard
  umount /home/nemo
  umount /mnt/sdcard2
fi

my df output looks like this:

Code:

[nemo@localhost ~]$ df -h

/dev/mmcblk1p1         60G  2.6G   54G   5% /home/nemo
/dev/mmcblk1p1         60G  2.6G   54G   5% /data/sdcard
tmpfs                 407M     0  407M   0% /mnt/asec

/dev/mmcblk1p1         60G  2.6G   54G   5% /home/nemo
/dev/mmcblk1p1         60G  2.6G   54G   5% /data/sdcard

Now i added a condition:

Code:

if [ "$ACTION" = "add" ]; then
  if [ $(mount | grep -c /mnt/sdcard2) != 1 ]; then
    mount /dev/mmcblk1p1 /mnt/sdcard2
    mount -o bind /mnt/sdcard2/.home /home/nemo
    mount -o bind /mnt/sdcard2/.android /data/sdcard
  fi
else
  umount /data/sdcard
  umount /home/nemo
  umount /mnt/sdcard2
fi

and the output looks like this:

Code:

[nemo@localhost ~]$ df -h
