Use Applications on post-boot mounted SD card?
From this XDA discussion:


  Create a script in /etc/init.d to do it. You'll need to remount / to
  read+write first though.


And solution:


  Thanks for your help! I'm quite firm in shell-operations, I just
  didn't think I could just put a script to /etc/init.d! :) 
  
  I'v created a shell-script named 07sdcard and with the content: Code:
  
  #!/system/bin/sh rootrw ln -s /mnt/external1 /sdcard-ext rootro
  
  Works geat! :)
