I think I've found a bug in apt-get :
Just now I tried the following :
# apt-get -t unstable install python2.1-numeric -s

Note that the first invocation says it is going to upgrade (not
remove!) python-numeric. However it is then going to remove several
packages that depend on it. In the second invocation it correctly
achieves the result the first one requests.
Why should the first invocation remove stuff if the second one
doesn't? (and why would it remove the stuff anyways?)
