</I>><i> Wherever this can be done, it usually is. Multiple versions of
</I>><i> libraries can coexist in Linux, so if the new version requires new
</I>><i> libraries, there's no conflict.
</I>><i>
</I>><i> The dependencies that cause problems are, for example, the situation
</I>><i> where you can only have one of a certain service provider and its users
</I>><i> are bound to it by an API which changes between the release version and
</I>><i> the new version you want to install. For example, if A, B, C, D, E all
</I>><i> use F, and the new version of C has been changed to use the
</I>><i> (incompatible) API of the new version of F, you'd have to install all 6.
</I>><i>
</I>><i>
</I>><i>
</I>
So, in terms of space used for this, if you had to install all 6, would
this tax the system so much and risk filling up the hardrive needlessly.
If not, would this cause your installation to misbehave.
It not, if a rollback were done, could all 6 as well as the new F be
removed and the old version restored?
If this is possible, would this have an impact on devs preparing
Backport versions with rollbacks?
