perfect explanation, apart from the fact that the installers partitioner
is called partman (and thus partman-udeb is used)

and yes, the live installer is just a different frontend. 
in the backend all debian-installer pieces are used, the installation
*process* is very different though (ubiquity copies the content of the
live filesystem and removes unwanted packages/configurations in the
target system while the alternate installer installs package by package
(which is significantly slower))
