grml-live is a build system for creating a Grml and Debian based Linux Live system. The build system is based on FAI (Fully Automatic Installation).
Building a Debian based 64bit live system is as simple as running:
# grml-live -s sid -a amd64 -c GRMLBASE,GRML_MEDIUM,AMD64
You can fully customize the build process, including adding additional software and your very own configuration files.
