First option is to rely on distro and every distro behaves differently in such cases, some of them won't change anything till their last user dies :) and others more dynamic with more up-to-date packages already adopted our default. Second option is to use numerous OFED stacks, which are expected to provide full upgrade to all components which will work smoothly. Users who upgrade their system from live upstream repo are expected to be proficient enough to be deal with change of defaults. Thanks > > -Denny
