I have a few dozens of Debian boxes which I want to keep up to date in a deterministic fashion, and also follow the
Engineering => Pre-Prod => Prod routine with a deterministic staging process.
Ideal world for me would be to have some sort of 'patch level ID' at hand, like
2022-01-10.e28de15cc1 and be able to say
apt upgrade --to 2022-01-10.e28de15cc1, but I've not found anything remotely similar.
I probably can hash the output of
apt list --installed after upgrading the first box and simulate the concept, but am really wondering why no one has done it, is my mental model of keeping penguins tidy completely off here?
