For now, I’m just running both: qubesctl
(Salt / Qubes Updater) first in case it does any Salty things, then the old qubes-dom0-update
in case the first one missed anything.
I understand why you want this, but I believe it would be the wrong solution to the problem. Instead, the entire update system should be set up in such a way that you don’t feel the need to manually double-check its work. The fact that a user feels the need to make sure that the system is doing its job is a sign that there is something wrong with the system (or possibly with the user’s expectation). The solution is to fix that problem (or realign the user’s expectations), not turn the user into a micromanager of mundane machine monotony.
@deeplow might know the answer to this.
