glogin is a program that can be used to cause a terminal (usually a virtual console) to be logged in automatically, without having to type a userid and password. Stick it in place of getty in /etc/inittab to have terminals come up logged in and at a shell prompt at every boot. Same purpose as 'alogin', but you use it a little differently, and it does a little more of the usual login stuff. It is a simple Perl program, and can be easily customized.
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.
