Well, the basic installs are all supposed to propose an initial set of
selected services (a kernel, a basic running environment, OpenOffice,
editors, at least one desktop, a mailer, a browser, ....). The packages
corresponding to these services should be marked as explicit and all the
others implicit.
If this is difficult to achieve, then mark everything as explicit at
install time and this scheme will work essentially for user added
packages and their dependencies...
This still has quite some value. Believe me, the number of packages
installed just to solve dependencies is quite high once the user start
to ask for some addons.
