Ok so today is not my day, as I managed to also break sshd on everything
but RHEL 7 while trying to secure everything.

 Hopefully, I was able to fix, but if you see jenkins job failure
between 18h40 and 18h55 UTC, that's me.

I suspect it to be a bug somewhere in salt, since it doesn't correctly
change the file correctly on RHEL 6 while it work with RHEL 7.
