Re: [Nix-dev] nixops - nix-channel per machine

I got the _module.args.pkgs to (almost) work but I think it somehow
mixes up the two nixpkgs versions (running on unstable, overriding
_module.args.pkgs to stable):

 Hi Rob  Nicolas,

 thank you for your suggestions.

 The option -I nixpkgs=/path/to/your/nixpkgs sets the nixpkgs globally
 for nixops.  That is not what I need.

 I have tried using nixops set-attrs, but that is also doesn't allow me
 to use stable for one machine and unstable for the other.

 Maybe this could work if I created two separate networks depending on
 nixpks.  But this is not a nice workaround.

 It looks like the module suggestion might be what I need but that gives
 me an error:

error: Module `foo/configuration.nix' has an unsupported attribute
`boot'. This is caused by assignments to the top-level attributes
`config' or `options'.  (use ‘--show-trace’ to show detailed location
information) error: evaluation of the deployment specification failed

 It seems that I am not allowed to change that.  Moreover, it doesn't
 seem to be the same as specifying a different nixos-channel.

 What I need is something like:

 test-logical.nix:

 {
   network.description = test network;
   foo = with-stable-channel ./foo/configuration.nix;
   bar = with-unstable-channel ./bar/configuration.nix;
 }

 Is there a way to achieve that?

 Thanks a lot!

Re: [Nix-dev] nixops - nix-channel per machine

2015-07-27 Thread Nicolas Pierron 
The problem of using the `_module.args.pkgs` is that you have the
NixOS module system of the nix-channel, but the package resolution of
the version that you specified.  The error that you are seeing is that
the latest module might use a package which got packaged/renamed
recently.

Strangely `pkgs.ipset` does not seems to be used, apart from being
listed as an non-literal example (which is a bug) [1].
One option would be for you to make a dummy derivation for ipset, or
use the one from the latest nixpkgs.
