Interesting article. I like this complicated technical stuff. :-) Allthough I don't have much experience with AIX (due to OS/390 running on the AS/400), many things mentioned in the article are understandable, obvious, logical and expectable when you're coming from a UNIX background. So no matter which particular kind of UNIX or Linux you're using, most things look familiar.
The alternative to the runlevels is the use of an rc script and the rc.d/ entries, such as it is the case in the FreeBSD OS. Refer to "man boot", "man loader", "man init" and "man rc" for further education.
Another interesting read: "The magic garden explained" by Goodheart and Cox, pp 48, 273.
I already hear someone screaming: "But the PC does it on its own! I don't want to know anything!" :-)
