How to root a LG-E405?

I wanted to do this because it's a small phone so moving to the sdcard is a good option to me so... anyone can help me?

I am a linux (OpenSuse) user so if there a solution using the terminal or something it's great!

about the phone:
phone - LG-E404.
Android - 2.3.6
Kernel - 2.6.38.6-perf+
compilation - GRK39F
Software Version - V10f-SEP-14-1012
