hello, i just installed NixOS following the manual procedure (http://hydra.nixos.org/build/106220/download/1/nixos/manual.html). fyi after running 'nixos-checkout' as per section 1.4, subversion did not appear to have been installed. i installed it with 'nix-env -i subversion' and continued. is the manual out of date or did something go wrong? cheers, gs
