Why: I have several machines (currently only one on NixOS, actively used, another one not used by now). I have the configuration.nix split into several files and put everything under version control. I have several sets of packages (base, gaming, development, media, etc) and I have one main file for each host. This way I can do DRY. I put a new package in, say, developPackages.nix and all new machines get it after a short git pull nixos-rebuild switch.

Re: [Nix-dev] NixOS on a machine with only one user
Assuming bigger things usually gives you a better or at least more scalable result, and in most cases the additional cost is very close to zero. For example every single-disk system I set up uses a two-disk RAID array with one missing disk from the point of view of mdadm. If it does happen that I actually want to add more disks, it will be a few short online commands to do it instead of a tedious reinstallation of the entire system, and it costs only a few megabytes. The additional disk might as well be an external emergency disk that starts synchronising as soon as I plug it in. How did you manage to make mdadm do that? It allows you to create arrays with missing disks, and you can activate them as long as enough disks are present. It's like creating an array with a failed disk right from the beginning: mdadm --create /dev/md/blah-system \ -l 1 -n 2 \ /dev/sda2 missing Notice the `missing` argument. It tells mdadm that the first disk is `/dev/sda2` and the second disk is currently missing. When you plug in a second disk, just add it to the array. When you plug in a third disk, convert the array to RAID5 (can be done online in the background, see `--grow`) and add the third disk. And so on.

Re: [Nix-dev] NixOS on a machine with only one user
NixOS noob here. I'm using NixOS on a machine with only one user (me). What's the best strategy for installing packages? [...] Installing into a normal user profile In general I tend to just assume that my system is an actual multi-user system. I'm a normal user, so I don't make any assumptions on the way imaginary fellow users use their account. A very small number of packages will have to be used by the majority of the users on the system, for example because they are relevant to the network topology or purpose. Most of them will be installed in the form of NixOS services. All other packages are user-specific. Installing user packages into the user profile has the additional advantage that it is safe and secure to install your own packages, which you may want to do from time to time, perhaps because you may want to use Nixpkgs-master for some bleeding edge version or because you may want to use Nix for a custom package or development. Remember that Nix handles not only code. You can equally well write and deploy a bunch of static files using it. Assuming bigger things usually gives you a better or at least more scalable result, and in most cases the additional cost is very close to zero. For example every single-disk system I set up uses a two-disk RAID array with one missing disk from the point of view of mdadm. If it does happen that I actually want to add more disks, it will be a few short online commands to do it instead of a tedious reinstallation of the entire system, and it costs only a few megabytes. The additional disk might as well be an external emergency disk that starts synchronising as soon as I plug it in. Fortunately this is possible with NixOS. Many distributions, including all Anaconda-based ones (RHEL, CentOS, Fedora, etc.), do not allow you to do this.

Re: [Nix-dev] NixOS on a machine with only one user
Do as you will. I keep my system profile as minimal as I can. And my user profile consists of several groups of pkgs. I have them in my ~/.nixpkgs/config [1]. Firstly I just install via `nix-env -i`, if I like the pkgs and I need it I'm writing it into my [1] to one of the groups (env).

Which I do. Hi Amy, I also use NixOS on machines where I am the sole user. I try out packages in the normal user profile first with `nix-env -i` and then if I end up sticking with it, move it into the global system environment in `/etc/nixos/configuration.nix`. I try to keep my user profile minimal or empty. I am also very new to NixOS, but the above method seems to work well. I keep track of the system configuration with git, so that's a nice added bonus. -L ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev

Installing into the global system environment - or - Installing into a normal user profile - or - Installing using nix-shell -p. This is what I use to install simple packages such as cli tools. More often than not, I end up not using that utility for more than the current task, so it's very convenient for the software to disappear once you close the shell. If you use something often enough to get tired of pulling it in via nix-shell, then maybe it's worth installing permanently. ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
