The cached debuginfo is a really cool concept. But it wont solve the 
problem of simplifying the use of systemtap for the customers. From a 
support standpoint if a customer system is missing a debug tool (or some 
dependent component) the tool may as well not exist! If it comes down to 
fix the debug tool or find another approach to solve the customers 
problem the later will generally win. To make stap successful we need to 
get people using it and providing feedback, let's make it as easy as 
possible to use. All dependencies must be installed when selecting a 
product for install.
