Service Management
- In NixOS, all system services are started and monitored using the systemd program. Systemd is the “init” process of the system (i.e. PID 1), the parent of all other processes. It manages a set of so-called “units”, which can be things like system services (programs), but also mount points, swap files, devices, targets (groups of units) and more. Units can have complex dependencies; for instance, one unit can require that another unit must be successfully started before the first unit can be started. When the system boots, it starts a unit named default.target; the dependencies of this unit cause all system services to be started, file systems to be mounted, swap files to be activated, and so on.

Description
+
- This command updates the system so that it corresponds to the configuration specified in /etc/nixos/configuration.nix. Thus, every time you modify /etc/nixos/configuration.nix or any NixOS module, you must run nixos-rebuild to make the changes take effect. It builds the new system in /nix/store, runs its activation script, and stop and (re)starts any system services if needed. Please note that user services need to be started manually as they aren't detected by the activation script at the moment.

NixOS now distributes the latest version of every single package registered on Hackage -- well in excess of 8,000 Haskell packages. Detailed instructions on how to use that infrastructure can be found in the User's Guide to the Haskell Infrastructure. Users migrating from an earlier release may find helpful information below, in the list of backwards-incompatible changes. Furthermore, we distribute 51(!) additional Haskell package sets that provide every single LTS Haskell release since version 0.0 as well as the most recent Stackage Nightly snapshot.

- Previous versions of Nixpkgs had support for all versions of the LTS Haskell package set. That support has been dropped. The previously provided haskell.packages.lts-x_y package sets still exist in name to aviod breaking user code, but these package sets don't actually contain the versions mandated by the corresponding LTS release. Instead, our package set it loosely based on the latest available LTS release, i.e. LTS 7.x at the time of this writing. New releases of NixOS and Nixpkgs will drop those old names entirely. The motivation for this change has been discussed at length on the nix-dev mailing list and in Github issue #14897. Development strategies for Haskell hackers who want to rely on Nix and NixOS have been described in another nix-dev article.

Furthermore, negative caching of host lookups is also disabled now by default. This should fix the issue of dns lookups failing in the presence of an unreliable network.

- The intel driver has been removed from the default list of X.org video drivers. The modesetting driver should take over automatically, it is better maintained upstream and has less problems with advanced X11 features. This can lead to a change in the output names used by xrandr. Some performance regressions on some GPU models might happen. Some OpenCL and VA-API applications might also break (Beignet seems to provide OpenCL support with modesetting driver, too).

Client authorization and TLS
- By default, any user who can connect to a FoundationDB process with the correct cluster configuration can access anything. FoundationDB uses a pluggable design to transport security, and out of the box it supports a LibreSSL-based plugin for TLS support. This plugin not only does in-flight encryption, but also performs client authorization based on the given endpoint's certificate chain. For example, a FoundationDB server may be configured to only accept client connections over TLS, where the client TLS certificate is from organization Acme Co in the Research and Development unit.

Backups and Disaster Recovery
- The usual rules for doing FoundationDB backups apply on NixOS as written in the FoundationDB manual. However, one important difference is the security profile for NixOS: by default, the foundationdb systemd unit uses Linux namespaces to restrict write access to the system, except for the log directory, data directory, and the /etc/foundationdb/ directory.
