[RFC] Upgrade to a package with all its dependency without network

[Marco <koansoftware@gmail.com>]

Hello,
I need to be able to upgrade to a package with all its dependency chain 
on a target system that does not have access to the network.

I'm trying to understand what may be the best and also the simplest 
solution.
Perhaps there is already this functionality in OE/Yocto?

I thought to implement a new opkg feture so that I can to generate the 
list of dependencies of a package and then extract the packages from 
OE/Yocto using a script or an application.

Another possibility would be to extend the operation of bitbake so I 
pull out the package and dependencies putting them in a dedicated 
directory to be moved on the target for the update.

For now I'm just analyzing what may be the possibilities and I'd love to 
have any comments or advice from someone more experienced than me on 
this topic.

Thanks
