That makes perfect sense. Running debian containers on the el6 kernel
on a centos node before has shown me that there are no fundamental
issues with the debian toolchain or command line binaries running on the
el6-kernel-compiled-on-el6, but it makes sense that there would be a lot
more possibilities of bugs compiling it on debian directly.
