Perhaps what we need is a meta-installer that runs standard installers but
ticks check boxes and sets or clears options that tell the app to not
install adware/toolbars/plug-ins, maximizes the privacy settings, turns off
Whenever I install something, I already make notes about what I
ticked/set/cleared so I can do it quickly the next time I need to install
the same thing. Notes like this in an appropriate format--from thousands
of users--can serve as the config file for the meta-installer.
Since the meta-installer would run the applications' own installers, there
shouldn't be objections from commercial vendors since it wouldn't be
repackaging their products.
