The goal of Cheix USB is a Linux image executing from a USB storage device into a running OS, either Linux or Windows, so that the host machine does not have to support booting from the USB device. The root filesystem and boot partitions are read-only to preserve the USB device. All writes are done in a tmpfs. The only writes to the USB storage device are those explicitly made by the user. Cheix's ISO can currently be used to create either a bootable USB or a hard-drive installation.
Sous-marin Linux is a small, pure, individualized Slackware installation system using only scripts and a minimum of resources. Sous-marin's utilities allow you to create an installer CD and tagfiles, choose the minimum of pure Slackware packages you need, and then FTP/HTTP install the system over the Net. It also includes sous-marin tools, formerly SlackBash scripts. These tools allow you to analyze any Slackware installation for missing libraries, files not in packages, packages dependencies, and so forth.
