You can install a couple of i686 packages because you want them and not get all multilib packages. But whatever approach one wants is fine. -------------- next part -------------- A non-text attachment was scrubbed...

BTW - some x86_64 package files get "touched" by un/installing the corresponding i?86 packages. I usually reinstall the x86_64 package after removing the i?86 package if rpm -V %{NAME} shows such "differences" - for example timestamp mismatch. -- LF
