cfgsh is a configuration shell utility that is intended to be used for configuring embedded systems. It is meant to replace the normal combination of utilities including ifconfig, route, startup scripts, and configuration files with a single program that implements the same functionality in a manner more consistent with the embedded system world.
sash-plus-patches is a collection of patches for the well known standalone shell, sash. The key features are the chroot, pivot_root, and losetup functions. These functions provide interfaces to the respective Linux system calls. They are especially useful when sash is used in a initial ramdisk ("initrd") environment. In addition, simple shell variable expansion support has been added.
