First thing I do after a install is disable nepomuk, strigi(not with 4.10.2) and akonadi, except for this install with KDE 4.10.2. for testing, it is the best since the *4* series, but, still sucks
Anyway this could be done during the build process, I don't think so, but asked anyways in the sake of lite
Until those packages are not needed to build/install/operate it will be hard to make a truly lite KDE IMHO
