The RACF subsystem gets started out if ICHSEC00, which is invoked out of IPL. If I recall correctly, both ACF2 and Top Secret provide a replacement for ICHSEC00 (probably the same code for both products).

That helped a lot. One of the questions I am trying to answer is "who is starting RACF during IPL". It's not in COMMNDxx.
