That said, Erwin, I don't have an answer to your question. Probably stricter
constraints in the packages may help, but not completely and it may be
complicated to implement.
Out of curiosity, how would the apt system have to change - strictly in theory - for something like this to be achieved?
That is a question we are facing since long, and apt does not provide a
solution. We want to force that updates can only be done in lockstep,
that is, packages cannot be updated to new major versions without
updating all.
But unfortunately, apt doesn't have an easy solution for that.
One idea was to make a virtual "abi package" (like we do for the PIM
packages) and inject dependencies so that each package depends on the
virtual abi package.
But this is also not very nice and easy a solution.
