Committing the aufs2.1 patch by Shea Levy. His comments: * My motivation for this patch is that kernels < 2.6.36 contain an e1000e that does not support the ethernet card that is part of the chipset for the second-generation Core-i Intel CPUs, so in order to have a more useful livecd I needed to get aufs working with a newer kernel, and 2.6.37 is the latest kernel with an official aufs release. * All sources are downloaded with fetchgit. This is because the aufs upstream doesn't provide release tarballs, they just add a tag to their git tree for an official release. * The make target for the aufs2.1 headers uses a Makefile in the kernel build directory that requires that unifdef be in the scripts/ subdirectory of the build directory. The way I've dealt with this here is by adding "make $makeFlags -C scripts unifdef" to the postBuild in the kernel builder. Since the builder is used by all kernel versions, this will require rebuilding every kernel and kernel-dependent package if the patch is accepted, so one alternative I thought of would be to create a fake kernel build directory where everything is symlinked to the real build directory except scripts/, which is first copied and then make unifdef is run before building aufs2.1. If that more complicated solution is preferred, or if anyone has ideas for another one, I can do that and submit a new patch. * The patch was tested by building a livecd ISO that uses it, then running the ISO from within virtualbox and installing aufs2.1-util from within the livecd environment. * The livecd was built using installation-cd-minimal.nix, with two changes to the Nixos tree: 1. boot.kernelPackages = pkgs.linuxPackages_2_6_37 was added to profiles/minimal.nix 2. config.boot.kernelPackages.aufs2 was changed to config.boot.kernelPackages.aufs2_1 in iso-image.nix I would have preferred to keep all changes within profiles/minimal.nix, but I couldn't figure out how to override iso-image.nix's definition of boot.extraModulePackages. Livecds that use an older kernel can't be built with this iso-image.nix, since we don't have aufs2.1 for them (just aufs2). If someone can point me to how I can override things set in iso-image.nix, I'd appreciate it. make -C scripts unifdef compiles the unifdef application in the scripts/ directory, and when Nix copies over the build tree to $out/lib/modules/$version/build for kernel modules to reference, it copies over all of scripts/ except the .o files. I can't speak for other kernel versions, but at the least for 2.6.37.1 unifdef is not built by default. If you look at the Makefile in scripts, unifdef is listed under a comment saying that the following programs are only built on-demand. svn path=/nixpkgs/trunk/; revision=26548
