From 4bee34dcc5e6886aac8c868410f12a670da03062 Mon Sep 17 00:00:00 2001 From: Emmanuel Rosa Date: Fri, 2 Jun 2017 20:58:41 -0400 Subject: doc: clarify building-nixos CD/DVD instructions This change updates the instructions for building a NixOS ISO so that it's clear how to do it. Previously, the instructions stated to set NIXOS_CONFIG prior to running `nix-build`, yet the example provided by-passed NIXOS_CONFIG anyway. But the *really* important missing piece is the need for nixos/default.nix. See #21840. This change removes the NIXOS_CONFIG verbiage, and adds steps to clone nixpkgs and (most importantly) cd'ing into nixpkgs/nixos. That way, the reader may think: *Oh, so I need a default.nix and a configuration.nix. Ahhh, OK.* I purposely added the redundant default.nix argument. --- nixos/doc/manual/development/building-nixos.xml | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/nixos/doc/manual/development/building-nixos.xml b/nixos/doc/manual/development/building-nixos.xml index 150fa1d7017e..2f963f8666f1 100644 --- a/nixos/doc/manual/development/building-nixos.xml +++ b/nixos/doc/manual/development/building-nixos.xml @@ -12,12 +12,12 @@ your configuration.nix to configure the system that would be installed on the CD.
