Snapd packages restart in rsync style matter when update/install

[Artur]

Hi,

I am coming from http://askubuntu.com/questions/788237/snappy-sharing-resources-and-updates/789205#789205 where I was encouraged to raise this bug/feature request.

I am working in an environment with rather limited connectivity. Currently we are executing updates by rsyncing files over to remote hosts using appending etc so that if the connectivity fails, we can pick up where we left and not loose data (imagine running update for 1+ GB of data and having to restart every time wifi becomes flaky).

It would be really useful if snapd could do this automatically. Since snappy packages are already versioned and (I believe) unique by revision, there should be no problem figuring out what packages are to be loaded and have been partially downloaded already.

I hope that all makes sense :)

Thanks for this great technology!
