ISOLINUX is part of a family--SYSLINUX for booting from hard drives, 
ISOLINUX for booting from CDs, and PXELINUX for booting over the 
network.  The configuration is nearly identical for all three.

Strictly speaking, you don't really even need the rescue disk.  It's 
surprisingly easy to build a complete Linux system from scratch using 
uclibc and busybox.  Just build busybox statically linked to uclibc 
(amazingly enough, the last time I did that, the static uclibc busybox 
was smaller then the dynamically linked glibc busybox) and install it 
to a temp directory.  Then create a couple extra directories (/dev, 
/tmp, /etc), populate /dev, create a short /etc/passwd and /etc/group, 
and you should have a bootable Linux image in under 1 MB.  Add asterisk 
to that, and you'll be ready to go.
