There are now over 3000 lines of (mainly perl) script in the TeX  
i-Package alone, of which 650 shared between actions (install,  
configure, uninstall). A total of 150kB script.


Anyway, I plan to do this as with ConTeXt indeed. Anyway, this is a  
consequence of the philosophy of i-Installer. There is no tight  
integration between i-Packages and each i-Package should be as  
self-sufficient as possible. This improves durability and  
maintainability as well as the possibility to mix and match install  

Basically, people should not need to be afraid to install because the  
damage it could do should be severely limited. Hence, installing the  
LaTeX updater is reversible. If it doesn't work for you: uninstall and  
you're back to your previous situation. Or at least that is the
