title: Package synchronization with opkg
body: <p>We're using the BeagleBone Black running Angstrom Linux and the opkg package manager to power some of our systems. We need to ensure that we have consistent and reliable access to specific versions of opkg packages. I've set up an in-house opkg repository. Is there any way to sync packages between repositories ? e.g. I'd like to copy specific packages from public / not always accessible repositories to our internal repository, both for speed and reliable access.</p>
