I consider to go back to a minimal Ubuntu 8.04 and install it's rt-kernel only and from there install anything I need from source. The 8.04 was rock stable in the beginning, but I suspect that the RT-kernel was messed up in a later upgrade. If I don't run a apt-get upgrade ever when I have that system, then it will be production ready again. The security is not a big issue, because the network is disabled (except when I have to be online with it).
