This is a squashed commit of the following: commit 0dccab9f417b406f5d4aedc81900fc7b2f16c9f6 Author: Eelco Dolstra <eelco.dolstra@logicblox.com> Date: Thu Jul 2 00:30:16 2015 +0200 Typo commit 2cd28517b13524c242c7758783b0b2d8250fdded Author: Ludovic Courtès <ludo@gnu.org> Date: Wed Jul 1 14:56:34 2015 +0200 Preserve supplementary groups of build users The following patch is an attempt to address this bug (see <http://bugs.gnu.org/18994>) by preserving the supplementary groups of build users in the build environment. In practice, I would expect that supplementary groups would contain only one or two groups: the build users group, and possibly the “kvm” group.

For instance, if we can't substitute a fetchgit call, then we have to download/build git and all its dependencies. Partially reverts 5558652709f27e8a887580b77b93c705659d7a4b and adds a new derivation attribute "allowSubstitutes" to specify whether a derivation may be substituted.
