Not that this particularly belongs to comp.unix.solaris, but I thought I'd
corrrect a few things just for drill.
It doesn't sound much like you've seen an RS/6000 running AIX. It does have
rc.{nfs,tcpip,net}, and various other BSD-like things you mentioned. E.g., AIX
relies on a proprietary database for its on-line hypertext documentation.
They've re-written man(1) so that it both knows about those and the usual man
page directories.
Actually, to be more accurate, for some things it uses the underlying "Object
Data Manager" as an info repository, e.g., what TCP/IP services are currently
running, what file systems exists, and so on. The "normal" files are there only
for compatibility. If you change them, you typically have to run a program to
inform the daemons that things have changed.
In short, AIX is quite unlike BSD and Sys V under the covers. If you want the
covers on, it still may be less like them than you want. On the other hand,
some of the differences are appealing...
