In current, almost Yocto Project users have to select software packages before building. This could cause the problem of managing packages when add, uninstall and upgrade packages. This presentation will give an introduction about how to use package management tool named "SMART" to solve this problem. By taking advantage of this tool, it is easy to add, uninstall and upgrade software packages without rebuild root filesystem to avoid the fragmentation.
