Let me rephrase the question. Is it possible to build a highly available system on nix such that SLA uptimes of 9 9s. (99.9999999 % uptime) are achievable?
If so what primitives does nix offer to allow this to happen? Such primitives should be: the ability for nix to invoke the hotswapping capabilities of a live running system. Now just connecting to Erlang and making changes isn't good enough. Why? - nix cannot see those "imperative" changes. Git vs svn, git takes the global view and svn the file view. Git got it right, you need to factor in the entire repo's changes. Nix gets it right too by looking at this from an entire system perspective, so I'm seeking a way to introduce change to a live fractalide system from a nix level, though it mustn't be a "connect to fractalide via ssh and change it there" approach. Making changes to Erlang via ssh under Nix management is like having a declarative system then introducing imperative mechanisms. I need a formalized method to ensure global determinism yet be able to make changes to a live running system from nix. Are there any Erlangers here who achieve huge uptimes on nix? If so how do you do it? How do you make use of Erlang's hotswapping mechanisms yet retain the lovely system wide determinism nix offers. kr/sjm _______________________________________________ nix-dev mailing list [email protected] http://lists.science.uu.nl/mailman/listinfo/nix-dev
