This is the FireballISO1.4, with over two years of updates and Gentoo configuration changes, and slightly updated documentation. It was originally built and released quickly to allow volunteers to have an updated version for their testing, but I'm promoting it to the latest version so people can find it more easily. Please let me know if there are any issues (firstname.lastname@example.org).
FireballISO1.4.1 with new features will be released when it's ready, but lack of time and other issues (like the hardened-sources kernel package being discontinued - I'm exploring alternatives for secure kernels) keep delaying this. I welcome any assistance in meeting FireballISO's goals!
