Comment 1 for bug 1325604

* only one question is left and is related to linaro-cp
* All the addition on top of custom AMI are hot fixes, documented in init and definitely not 70 lines
* linaro-cp is used on dedicated slave, hence not on AMI
* session timeout is too short and is unrelated to any of the issues raised above

so if you feel that AMI setup starts to be disorganized, it's because you aren't in the loop of some of the changes.
