Only by comparing it to older images ... the SystemTracer has been  
used on a Smalltalk-80 image to convert it to the Squeak object  
format. This just copied object identities, so you could say the  
objects in there are still the same. But Smalltalk-80 has not been  
bootstrapped either, IIRC someone mentioned the last bootstrapping  
happened with Smalltalk-76, after that it was copied. So it might not  
be improbable that objects like nil, true, false see their 30th  
birthday soon ...
