It doesn't matter what the auxtype of a system file is.  SYS files ALWAYS load
at $2000; the auxtype is never even checked.
 
By using the pathname at $280, a SYS file can read and set its own auxtype...
might be useful for programs that need to save a few little bits of
information back to their own file.  Use the auxtype instead of opening and
writing the file... much faster.

I don't think there are any reserved auxtypes within the SYS filetype, but if
there are, I imagine I will hear about it for the above suggestion.  :)
