Ah yeah, indeed, I realized that when I read the sentence again... > I often wondered why it wasn't the case, but I've assumed so far that > there was probably a reason I just could not think of :) I can think one: autoremove and packages marked as automatically installed. When you install package B as a dependency of A, you install B as an automatically installed package, so that apt-get autoremove can get rid of it when A is no longer installed. If you lock to install package B, then unlock and lock again when you're about to install A, apt-get autoremove might have been invoked in the mean time and package B might not be present anymore. Sure, you can handle that too, but I really don't think it's worth the hassle. There might be a lot many more cases like this, and the benefit seems very insignificant.
