Update all domains for Qubes OS 4.0

[Jimmy Axenhus]

Hi!

A while ago I wrote a small Python-script to update all VMs at once.
I've now upgraded it for Qubes OS 4.0.
At the same time I decided to rewrite it in shell to avoid relying on
the Python API. Unless something drastically changes I expect this to
also work for future Qubes OS releases.

Embedded:

#!/bin/sh

for domain in $(qvm-ls --fields NAME,CLASS | \
    awk '($2 == "TemplateVM" || $2 == "StandaloneVM") {print $1}'); do
    qvm-run --service $domain qubes.InstallUpdatesGUI
done

sudo qubes-dom0-update
