Fat installer for multiple architectures in

### What is the idea?

Similar to having a thin online installer, it may be desirable to have a fat “offline” installer that bundles together multiple versions of packages that are optimized for different machines.

At extraction time. It could take the appropriate packages for the machine, all offline.

### Why is this needed?

Some systems are airgapped and they think that USB is better than reliable network.

I’m just trying to get things to work for my users without “asking them to download the right installer”

For now. We can consider the same CPU base architecture.
