Both eacj@theory.TC.Cornell.EDU (Julian Vrieslander) and
streater@unixhub.SLAC.Stanford.EDU (Tim Streater) have posted their
results from following Apple's sugestion and we either have crashes or
fonts in the system.
The most offen reported fonts left in the system file seem to be
Monico, Geneva, Chicago.
To restate the logic of my previous post:
"Though I could not get him [the Apple represenitive I talked to] to admit this 
is a bug in the installer, from the evidence it is QED (progression of logic)
that there is a bug. 
In this case the QED is a syllogism, which is a general true statement 
followed by a specific true statement and then a conclusion from the the 
two statements, can be used. For example:                      
All men are mortal                     
Charles Darwin was a man            
Therefore Charles Darwin was mortal
                                                       
The syllogism in the case of the System 7.1 installer is as follows:
1) Bug: a programing error; error in syntax or logic; the program does not
do what it is supposed to do (Dictionary of Computer Terms 3rd ed.)
2) System 7.1 installer can leave fonts in the system file which should not
be there. (From the Apple represenitive) or hang (Internet postings)
3) Therefore there is a bug in the System 7.1 installer."

The logic STILL applies.  The Installer is doing things it should not do
(Leaving fonts in the system file, hanging, not starting up at all)
and allowing you to install on your start up HD {error in logic; if you
must boot up from the installer then the installer should halt and
give a dialog box saying that you MUST startUp from the installer}

I looks like you missed the point; while my EXAMPLE was in error the
syllogism was and is still valid.  There is clearly a bug in the Installer
no matter how you or Apple want to avoid the syllogism. {The Quatra install
is another bug: Can't easy install-an error in both syntax and logic}
Claiming 'pilot error' when there were ways to prevent the installer from
working on an active system (Installer for 4.0.1, 6.0.3, and 6.0.5) is
just ignoring the fact that the programers goofed in either sysntax or logic.

is the truth" -- Sir Arthur Conan Doyle through Sherlock Holmes in The
