linux: Enable support for Self-Encrypting Drives
To quote block/Kconfig:

> Builds Logic for interfacing with Opal enabled controllers.
> Enabling this option enables users to setup/unlock/lock
> Locking ranges for SED devices using the Opal protocol.

Without `BLK_SED_OPAL`, it is impossible to resume from sleep when using
a locked self-encrypting drive.

This configuration option appeared in earlier kernels, but only reached
maturity in 4.14 according to discussion at:

- https://github.com/Drive-Trust-Alliance/sedutil/issues/90 and
- https://github.com/Drive-Trust-Alliance/sedutil/pull/190

This kernel option is enabled in the default kernels shipped with
Fedora, Debian, and other mainstream Linux distributions.

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:

% git remote add channels https://github.com/NixOS/nixpkgs-channels.git

For stability and maximum binary package support, it is recommended to maintain custom changes on top of one of the channels, e.g. nixos-18.09 for the latest release and nixos-unstable for the latest successful build of master:

% git remote update channels
% git rebase channels/nixos-18.09

For pull requests, please rebase onto nixpkgs master.

NixOS Linux distribution source code is located inside nixos/ folder.
