Expression for a buildEnv-based declarative user environment

This is one way of managing your user profile declaratively.

Alternatives include:

• an attrset-based nix-env-based environment, installed using nix-env -ir rather than nix-env --set. LnL has an overlay which shows a way of doing this.
• home-manager, which provides NixOS-like config for your $HOME

Note that this is incompatible with regular imperative use of nix-env, e.g. nix-env -iA nixpkgs.hello. It has the advantage of allowing the installation of multiple outputs of the same package much better than nix-env's builtin profile builder does.

Network Isolation of Services with Systemd

Network namespaces are an important component of containerization in Linux. A network namespace (netns) allows a running process to see different network interfaces, routes, and firewall rules from the rest of the system. There are a number of use cases for network namespaces, such as running multiple servers, testing/staging environments and providing isolation of services.

Creating a Network Namepsace

We begin by creating a generic systemd service for creating a named network namespace. I add the following to /usr/lib/systemd/system/netns@.service. In systemd, the @ mean the service takes a parameter which is passed to the unit via %i. E.g, we can run sudo systemctl start netns@webserver.service.
