AntiX is a really cool distro and when installing you can choose whether you want stable, testing, or unstable. Anti also makes a fantastic kernel.I'm downloading Canaima 4.0 Alpha right now to try install on my partner's computer. Debian-based and the official distro of her home country's government. Might not keep it but she wants to try it out.
I have a basic dual setup with Linux Debian and Windows 7 (Grub is my bootloader). However, since this machine will be donated to a friend that does not know a lot about computers, I would like to install a more user friendly Linux distro.
I suspect that if I try to install on top of Debian, the bootloader will be overwritten and hell will break loose.
