Why I did it The image size is too large, when there are multiple lazy packages and multiple platforms. It is not necessary to keep the lazy installation packages in multiple copies. For cisco image, the image size will reduce from 3.5G to 1.7G. How I did it Use symbol links to only keep one package for each of the lazy package. Make a new folder fsroot/platform/common Copy the lazy packages into the folder. When using a package in each of the platform, such as x86_64-grub, x86_64-8800_rp-r0, x86_64-8201_on-r0, etc, only make a symbol link to the package in the common folder.
