If I understand your question, you're asking if the processing of run levels is a fall-thru process. That is, to boot to runlevel 3, you first execute the startup scripts in the rc1.d, rc2.d before executing the startup scripts in rc3.d. If so, then I believe you are mistaken. It is my understanding that to switch to runlevel 3, the system executes only the startup or kill scripts in rc3.d (or, which ever run level you are switching too). Also, as Net Llama just said, all of the directory entries are symlinks to back to the init.d directory. Also, for what it's worth, after Caldera self-destructed, I decided to migrate to Debian. For an educational environment you might also what to take a look at Linux from Scratch.
