Re-signing packages will not change their name-evr-arch, so on urpmi/rpm
side packages does not have to be updated. But from a user point of view
they installed packages (then checked it) before the compromission, ie
when packages were trustable.

So in case of compromission packages must be resigned but I don't think
users have to reinstall it as their content won't changes.

In the case a packages is compromised (a package with malware is
introduced on the mirror) then we'll have to provide an update with a
clean package and in this specific case users will have to update it.
