Pre-production server
At this point, we are live. The site is still unknown. Some people are visiting it. We need
a server to test production configurations before committing them to production. For sure, the
site is still barely used so we can crash the whole thing and no one will notice. But we
have to have proper methodology.

Instead of installing a new server or using a VM, we decided to go the LXC container way. We tried to
run containers inside containers. We had a few issues and had to do little fixes, but the end result
is cool. One the development machine, it goes at the same speed in the pre-production container than
outside.

Here are the changes we had to do:

*Containers are using an IP in the network 192.168.122.0.
*Containers inside container can't use the same network. So we selected 192.168.124.0.
*Set lxc.seccomp to nothing. OK, this is less secure. But it is just to test that
the production configuration works.

Now, every programmer has its own preprod, configured exactly the same as production, running at full speed.
