That's not quite the whole story.  INIT code can be found in four
places at start up time:

  1. The System file: these are all basic and nowadays no one fiddles
     with them or is supposed to.  (Except viruses :-))  When INIT 31
     runs, it locates and executes the remaining three types of INITs.

  2. "Startup Documents", files with type INIT: these run at startup
     and are generally not used beyond that time (though the code they
     contain may stay active in memory as long as the Mac is up).

  3. "Control Panel Documents", files with type cdev: these are the
     things that show up in the control panel window.  They MAY have a
     component that runs at boot-up time, contained in an INIT code
     resource. 

  4. "Chooser Document", at least those files with type RDEV.  I don't
     actually know much about these, but I think they are used by file
     servers for instance.  These may also contain INIT segments.
     (Printer drivers also show up in "view-by-kind" as Chooser
     documents, but they don't contain INITs.)

So the Finder can show you all the Startup documents, true.  It will
also show you all the Control Panel documents and Chooser documents,
SOME of which MAY also contain init segments.
