Installer: have an option for restoring from backup

[deeplow]

The problem you're addressing (if any)

There are situation where a user installs a fresh Qubes version just to restore some backup. One can choose the default install and then not install the user vms (persona, vault, etc.).

The solution you'd like

UX-wise it's much easier to for users if they had an option that said "restore from backup", that would install the bare minimum necessary to restore from backup and start the restore utility on first start.

The value to a user, and who that user might be

This avoids situations where the user mistakenly does the full install and then ends up with debian-111.

Wouldn't it be debian-11-1? Anyway, the name confusion seems like a separate problem.

For this to be solved, the user can uncheck installing Debian template from the installer. If it was Fedora you were restoring, the same. One thing that could be done is rename the templates (random name or prefixed, exclude them from backup), this is missing a qvm-rename tool, which only has a GUI variant on Qube Manager (I tried to find related issue).

Not yet, but it's an easy fix: QubesOS/qubes-core-admin-client#410
