Sorry about that, my question is not clear because i have no experience in this area,
We sell black boxes to customers, ubuntu linux is running in such embedded system boxes. But no screen, no console. You can download packages to them from our windows utility as you know the ip, then our app running in the system will pick them up and starts the upgrade.
The requirement from the top is: customer should be able to upgrade kernel, file system, out app using apt-get install, or any of the combinations from these 3.
Also this upgrade should be able to handle all cases without technician on the site if possible: e.g. you lost power in the middle of upgrade, your new app has a bug and system won't start after upgrade, or your kernel has a bug and it just won't boot up...
Also in the system you are only allowed to keep 1 copy of kernel, 1 copy of fs, 2 copies of app. So if kernel is screwed up, you don't have a way to boot from another kernel easily.
Don't ask me why, management just doesn't listen to most engineers, and i have a family to feed.
So my 1st question is, with several package commands, which ones can handle above tasks.

From what i grasp, you are attempting to create a package. Before we help you, tell us why you are creating a package.
I suspect there is perhaps a better way to do what you desire.
