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.
Yard is a suite of Perl scripts for creating rescue disks (also called bootdisks) for Linux. A rescue disk is a self-contained Linux kernel and filesystem on a floppy, usually used when you can't (or don't want to) boot off your hard disk. A rescue disk usually contains utilities for diagnosing and manipulating hard disks and filesystems.
LILO-Splash-Screen Script-Fu is a script for the GIMP which helps you create fancy splash screens for use with LILO (and the boot-logo patch). It converts an RGB image to an indexed one, selecting appropriate colors for the image and a special region of interest (the current selection) where the boot menu shall reside. This is done by first duplicating the selection and its inversion, converting both to indexed images, then adding a modified color palette (ADD/SUB) required for the menu bar, and finally recombining all palette colors into a single 256 color palette.
