[Nix-dev] Providing more explicit nix installation instructions
Over the past couple months, I've installed nix about ten times on various systems, where the underlying system was either ubuntu, archlinux, centos, mac os x, or directly nixos. I've also set it up for administration through a user account, via sudo, and for multiple users. Sometimes things have worked out, sometimes they haven't. Usually, the documentation lacks a bit of explicit (sometimes vital) detail. Since I'll probably go through this processes occasionally in the future, I'd be willing to add my findings to the wiki or the documentation, if this would be of interest? Perhaps to start with: I wanted to install it on a Ubuntu 12.10 system from a user account, and noticed something weird: # Try to install the .deb $ sudo dpkg -i ~/Downloads/nix_1.3-1_amd64.deb # There were missing dependencies, so install them as follows: $ sudo apt-get update $ sudo apt-get install -f # Now this is the problem: $ sudo nix-channel --add http://nixos.org/channels/nixpkgs-unstable That created the file $HOME/.nix-channels in my USER home, but with owner root. Obviously not the correct behavior. The following `sudo nix-channel --update` failed (sorry, don't have the error message anymore). Any suggestions for a better way to do this? To get around the problem, I did something like the following: $ sudo rm ~/.nix-channels $ source /etc/profile.d/nix.sh The last command created ~/.nix-channels with the proper ownership and contents. I suppose it knew which channel to put in .nix-channels because of the first invocation of `nix-channel -add`? Should I have sourced nix.sh before calling `sudo nix-channel` the first time? Anyhow, after that, the following command *was* successful, and I could subsequently install software. $ sudo nix-channel --update Best regards, Ellis ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev

You can install firefox 18 explicitly by nix-env -i firefox-18.0-with-plugins (Incidentally, firefox 17.0.1 has known security vulnerabilities. Wouldn't that be an argument for making 18 the default, even if the expression isn't as well-tested?) I didn't know about the security vulnerabilities, but when I added firefox 18.0, I didn't know what to do about lowPrio, because sometimes we have had newer versions with lowPrio. I always end up using the latest, *if it works*. I guess you propose something similar.

[Nix-dev] mips64el: syntax error in 'replace-dependency.nix'
Hi,
I'm trying to install NixOS in a chroot. I'm using a tarball
(nixos-system-mips64el-linux.tar.xz) that I fetched several month ago.
So, the problem is the following error message.
# nix-env -i hello
error: syntax error, unexpected $undefined, expecting '}', at
`/nix/store/pax21mr1bmd7m7zlghb77hrsj3ay9jii-nixos-0.1pre4033_e844fed-96a834d/nixos/nixpkgs/pkgs/build-support/replace-dependency.nix:20:11'
(use `--show-trace' to show detailed location information)
Here is a line that raises the error:
{ drv, old-dependency, new-dependency }:
When I was using this tarball in the past, it worked fine. Is there a
new tarball?

[Nix-dev] [***SPAM***] HYDRA_DISALLOW_UNFREE=1 allows to install the Linux kernel from kernel.org
Hi, I've been told some time ago that it's possible to use NixOS without non-free packages if I run 'export HYDRA_DISALLOW_UNFREE=1'. Unfortunately, it allows to use a non-free version of the Linux kernel. Yes, I can change the corresponding recipe. But can this be done automatically? Also, are there any other non-free packages that can sneak in? Nikita P.S. The best solution would be to remove all non-free packages from the repos, but I understand that you won't agree. pgp0yNaunaup2.pgp Description: PGP signature ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
Re: [Nix-dev] mips64el: syntax error in 'replace-dependency.nix'
Hello,
The problem is not with the tarball per se, it's with nixpkgs. To fix
the issue, you can either update your nix version to at least nix 1.2,
or wait until
https://github.com/NixOS/nixpkgs/commit/5626c5cdfb6de664881eb8b79dd54a8f4ca19b8f
hits the nixpkgs channel so it will still work with older versions of nix.
Cheers,
Shea

Re: [Nix-dev] [***SPAM***] HYDRA_DISALLOW_UNFREE=1 allows to install the Linux kernel from kernel.org
Hello, HYDRA_DISALLOW_UNFREE was designed for our buildfarm, where unfree means not legally distributable. Since the kernel is legal to distribute despite the binary firmware blobs (I assume that's your objection?), HYDRA_DISALLOW_UNFREE will block it. In general, there's no automatic way to detect what is free and what is not, especially considering people's different definitions. HYDRA_DISALLOW_UNFREE depends on packagers specifying the license when they add an unfree package. If someone were to take the time to add meta attributes to each package that is free by their standards (or to every one that is not), it would be pretty easy to then provide a way for them to ensure their system only has those packages, but that initial work is not trivial.
