9 9s not unheard of in these circles, Google uptimes are a joke not worthy of mention.
There are systems that have been running for some 40 odd years in production that factor in changes to legal banking regulations, hardware, business logic etc. Erlang has a system called the Ericsson AXD301 which has achieved this time frame. Just because Nixos hasn't been around that long doesn't mean it can't have the primitives to allow for such feats. Its these primitives I'm enquiring about. So let's use a new, less controversial figure of 5 9s and keep on topic. The thing is, we're designing this system so that its governed by nix don't necessarily have to depend heavily on the runtime - I really don't want to go down the imperative route, by introducing imperative language concepts into our declarative language which is managed by another declarative language (nix). Besides just bringing in a single component with an OS Dependency demands we manage this change from nix level. We currently have a hack in place, that will resolve dependencies and give us a path to load a correctly compiled shared object into memory: https://github.com/fractalide/fractalide/blob/master/components/nucleus/find/component/src/lib.rs#L43 nasty and cringe worthy I know. Thanks for your pointer, I'll take a look at these activation scripts. Maybe this hack is the answer, and confine the dynamism to an ssh login al a Erlang style...
