su: System error - kernel 3.15

[gam-phon]

I have found an error in start.bash when running "su ghost << EOF". This happens when the kernel is 3.15. So to solve it downgrade to 3.14.

Check this issue on docker moby/moby#6792
This is a reference if you face this problem

Same error on Ubuntu Server 14.04 running kernel 3.16 with docker client/server version 1.0.1 :/
