Is there a way to run extra services during an offline upgrade? Qubes OS requires that a VM be running certain services at all times.

Extra services during offline upgrade

AFAIR, the "offline" upgrade really is just a special systemd target that gets activated when a specific symlink exists in the rootfs, and a successful update deletes that symlink.

So, yes, you can run extra services by making sure your systemd service file is configured to start in that target.
