feature request: do-release-upgrade --download-only
Binary package hint: update-manager
I would like to see a --download-only switch for do-release-upgrade, so that the network-dependent part of an over-the-net upgrade can be separated as much as possible from the local unpacking, configuration, and installation of the upgrade.
This would be similar to the -d switch available for aptitude (although, certainly, -d is already used for --devel in do-release-upgrade, so if there is to be a short version, it would have to be something different, perhaps -D)
A general use-case for this is fetching the bulk of the upgrade packages while on a cheaper or higher-capacity connection, and then completing the upgrade on a lower-capacity or more expensive connection.
For instance, I often go to conferences in the fall around release time, and have more than once thought it'd be fun to try to upgrade an altroot install during downtimes at the conference, or on the way there. But, inevitably, the conference network connections are overloaded, and I don't want to compound the problem by pulling down a full release upgrade.
Also, a bulk network download doesn't call for nearly the same amount of attention as does the configuration and installation process. Being able to fire-and-forget the download portion conserves attention and patience for dealing with the vagaries of whatever other upgrade challenges there might be.
