Traditionally, init is the program that starts all other programs.
It's the first userland program the kernel runs. In your case it sounds like
you might want to make a script to load your RTLinux modules and tell the
kernel to run that as init. Note that you will need an interpreter for the
script (ie /bin/bash), the script, your RTLinux program in the form of a
module, insmod (which comes with modutils), supporting libraries (ie libc)
unless you compile everything static, and lastly a place to put all this, ie a
file system of some sort (maybe a RAMdisk?). You might just want to start with
Nicholas McGuire's miniRTL and go from there.
