- Migrate from update-alternatives (bsc#1245830). - The APACHE_MPM environment variable now controls which MPM will be used. If an empty string is provided, the script-helpers file implements its own logic to pick an MPM from the currently installed ones. As at least one MPM is always required, this will work just fine.
