Well I can't think of a reasonable reason for leaving an old copy of  
Journal kicking around in /home/olpc/Activities (faint chance a dev is  
keeping old keep sakes). So that would be a rm, in my book. Unless you  
think there is a faint chance of the user booting back to some pre 6xx  
build and have it still work?

The Clac issue I guess is a special case in that that there was a  
'Calculate' from MIT that was replaced by Reinier's 'Calc' at some  
point (at least as I understand the history), so I'm guessing  
bundle_id didn't exist  (or perhaps now depreciated service thingy) so  
there's no way the updater would officially know to replace/remove  
Calc and replace with Calculate. This could be a special case for post  
cleanup, removing Calc if Calculate has been installed.

I guess it's a trade-off between fielding support questions, risk of  
deleting something the user actually wanted still, and complexity of  
the post install script (as it surly will grow over time). I don't  
claim to know enough to answer, just enough to ask the question :-)

P.S. what's the post install script called by the way? I'm sure I've  
seen it mentioned in passing or rushing past the console after an  
install, doing 'rainbow' type stuff I think, hence me invoking your  
name here.
