Yes (I didn't test it actually but I think I can have it), but it's
always the same problem: I have to trust "something" (a GPG key, an SSH
key, a VPN, a machine, whatever...) outside of the closed network.

The advantage of what I was trying to do in the first place (automatic
upgrades) is that I don't need to open a hole to access the machine as
long as there is no problem.
