Hello all, I'm new to this list. I just installed NixOS on a spare laptop of mine (with the minimum CD) by following the manual at http://hydra.nixos.org/build/1568621/download/1/nixos/manual.html. The system boots into the slim login manager at startup, since I enabled the services.xserver portion in /etc/nixos/configuration.nix.
Anyway, here are some questions. 1a. I've added a new user account with "useradd," per the manual, and have done a couple installations of software with `nix-env -i'. This is great, but I'm curious --- what is the preferred way to install software? The wiki page at http://nixos.org/wiki/Install/remove_software says that there are two ways to install software --- system-wide (by editing environment.systemPackages), and per-user (by just doing nix-env -i [package]). My understanding is that in order to get the advertised advantages of NixOS's rollback functionality, you have to do system-wide installs because the whole "nixos-rebuild" command only looks at /etc/nixos/configuration.nix. I.e., there is no way to rollback the system on a per-user basis. So, do most people on here have a very long environment.systemPackages definition in their configuration.nix, defining all system-wide packages? 1b. If I wanted zsh, git, and rxvt-unicode to be available system-wide, can I do: environment.systemPackages = [ pkgs.zsh pkgs.git pkgs.rxvt-unicode ]; in my configuration.nix? There does not seem to be any documentation regarding the syntax for this. 2. If I do "nix-env -i" as the root user, then the installation is only for the root user, correct? -Linus _______________________________________________ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
