@pauldoo@mastodon.scot @drakulix@social.dreampi.es the idea with atomic systems may be alright but the way it's typically implemented on the legacy base is no good at all the way i want it is making sure the underlying system seamlessly gives you the option without needing a bunch of crusty stuff on top start with a package manager and packaging that acts atomically and doesn't run random scripts in the middle of a transaction, limiting them to the end and making them idempotent make any dynamic configuration data (/etc /var) stateless make the system fully workable with a read-only root little and not-so-little things that make fundamental building blocks
