I also wonder, how "zypper dup" or DVD upgrade handles the downgraded packages.
Nicely, it is expected.
Nitpicking - all that zypper does is equivalent of "rpm -i --force --replacepkgs" which will install any version over any version. Whether RPM can actually be installed depends on changes between these two versions. There are known file layout changes that cannot be handled on RPM level (like replacing directory with symlink) - such changes must be caught by scripts. But old RPM version is not aware of layout change in new version of course ... Another example is splitting of single service in several independent ones, where old RPM cannot of course know it should enable old service. This is different from upgrade where new RPM version can be prepared to handle such cases. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
