Immutables are cool—I’ve been running Silverblue for over half a year now. However, this seems half baked?
Unless I’ve misunderstood, you can no longer use pacman (without losing your changes after the next update).
And arkdep itself is just a shell script without any tests or continuous integration. I would be skeptical of using such a tool to control the integrity of my system.
As others have said, ditch the cream cheese. It needs an acid like lemon juice or red wine vinegar. I would reduce the black pepper and add something with more flavour like red chile or jalapeños. I also like to top it with fresh whole cilantro or parsley for both flavour and texture. You could also use something like diced radish.
Pickled red onions are also easy and will take you far.
