  Since the MIMIX journal receivers are not both "Q" prefixed 
objects and located in either a "system library" or a "Q" prefixed 
pseudo-"user library", I would not expect the accounting of those 
objects to appear under a heading "i5/OS items".

  I would not be surprised however, to see all "Q" prefixed *JRNRCV 
objects in either a true "system library" or a pseudo-"user library" 
accounted under that section heading "i5/OS items", as a side effect 
of "ease of implementation" for the reporting facility.  Such an 
implementation is likely, because given any explicit validation of 
each *JRN by name & library classified as appropriately being part 
of the OS [according to some algorithm], and then accounting only 
the associated receivers for each of those journal objects, even 
that could not be ensured to be accurate accounting.

  I could not find a KB document that describes the various 
categories in the system "disk space report", although I seem to 
recall that there was such a document at one time.
