38 <para>A large number of packages have been converted to use the multiple outputs feature
39 of Nix to greatly reduce the amount of required disk space. This may require changes

41 Nixpkgs manual for more information. (Additional caveat to packagers: some packaging conventions
42 related to multiple-output packages
43 <link xlink:href="https://github.com/NixOS/nixpkgs/pull/14766">were changed</link>

104 a reasonably secure system without having to sacrifice too much
105 functionality. See <xref linkend="sec-grsecurity" /> for documentation
