Hello,
I've been reading some stuff about apt, dpkg and I wonder if it is
possible to have more control on package's dependencies. Is there other
package managers for debian that are able to support it?
I've found this at www.debian.org
" As you can see in the above example, APT also takes care of
removing packages which depend on the package you have asked to remove.
There is no way to remove a package using APT without also removing those
packages that depend on it.".
I hope this only matters to apt. :S
what is your goal here? Removing a package that another depends on would leave that other package broken and unusable (unless you get the dependencies outside the apt system). Package foo needs package bar to function. If you remove package bar, then package foo will be broken and will be removed as well.
