Yocto SDKs or images are currently deployed as monolithic archives.
Projects are more and more complex resulting to larger archives and 
consequently, SDKs or target images updates are not efficient at all.
This talk presents a new solution based on incremental updates and binary
packages deployment, which is closer to standard Linux distribution packaging. 
This solution offers an easy way to update development environment (SDK)
on the development machine and makes packages management simpler on the target side.
This allows among other to install a minimal set of packages in order to reduce the target filesystem size.
