The reliable way to do rollbacks is to:
1. Install Qubes OS on a btrfs file system.
2. Install the dnf / yum plugin that will snapshot your system right
before upgrades.
Slightly less convenient:
1. Migrate your Qubes OS to ZFS.
2. Manually ZFS snapshot your Qubes OS before dom0 / template upgrades.
