A CentOS 6 Live CD with TOMOYO kernel installed is available. http://tomoyo.sourceforge.jp/download.html I was making "TOMOYO + CentOS 5 Live CD" from "original CentOS 5 Live CD" by replacing kernel package using loopback mount. However, since CentOS 6 Live CD supports live installation method that depends on LVM snapshot image, I was not able to use such approach. I googled for anaconda's kickstart file and built this Live CD using it. Therefore, there might be slight difference between "original CentOS 6 Live CD" and "TOMOYO + CentOS 6 Live CD". Please report on this ML if you found problems which are specific to "TOMOYO + CentOS 6 Live CD". Regards.
