Re: [Nix-dev] How to use a previous build from hydra-server
If there are multiple channels (custom channels included) available, how
does Nix choose from which to install, and is there a way for us to pick a
preference?

Re: [Nix-dev] How to use a previous build from hydra-server
I believe it tries all of them that are on the search path ($NIX_PATH), and
picks the one with the latest version of whatever package you're installing
(highest version number). All dependencies come from the same channel
(though that channel might, in turn, import them from another channel). By
default nix will only put nixpkgs=/path/to/your/downloaded/nixpkgs/channel
in $NIX_PATH, so you'll need to add custom channels to that, too, if you
want to use them.
For the imperative mode (nix-env), you can pick by specifying the -f flag.
So for example, "nix-env -i firefox -f ''" will install Firefox
from the channel named nixpkgs. For a channel that isn't on $NIX_PATH, use
"... -f $HOME/.nix-defexpr/channels/nixpkgs" instead.
For NixOS' declarative mode (nixos-rebuild)'s environment.systemPackages,
instead of adding pkgs.whatever, add myOtherChannel.pkgs.whatever, where
myOtherChannel might be defined earlier as "import {}".
For NixOS service modules, the module's configuration typically include a
.pkg option, which you can change to a reference to wherever you want.

Re: [Nix-dev] How to use a previous build from hydra-server
You can import a package from a specific version of nixpkgs, independent of
the rest of your build, though it's a bit of a manual process.
First, check on Hydra which Git revision it is that you want to build (you
can see this on the Inputs tab, 144d13cf2cc6de28f8abe9e9e8c98f28ccf8fc59 in
this case). Then check what Nix's hash of that revision is, (either by
running nix-prefetch-git or by looking at the store path in the Inputs tab,
in this case phb6bdyhvnsx92mh78jysaavgviwqpbr). Then replace the reference
to the package with a reference to the package in that version of nixpkgs.
Now, with most NixOS modules you could do this by setting something like
services.mesos.pkg = (import (lib.fetchGit {
url = https://github.com/NixOS/nixpkgs.git;
rev = "144d13cf2cc6de28f8abe9e9e8c98f28ccf8fc59";
sha256 = "phb6bdyhvnsx92mh78jysaavgviwqpbr";
}) {}).pkgs.mesos;
However, from what I can tell, the mesos module (
https://github.com/NixOS/nixpkgs/blob/788800e437c4a0a25d95e217540bded68804b25e/nixos/modules/services/misc/mesos-slave.nix)
is one of the few modules that don't support replacing the package used.
So, uh, that's a problem that should probably be fixed, but won't really
help you right now. :/

Re: [Nix-dev] How to use a previous build from hydra-server
Hi Rok,
Thanks for reply. How should I fetch it? I mean how to tell the system to
use that particular build? Currently, when I say nixos-rebuild {boot |
switch} it assumes that that (which again I am not sure which one
it refers to when I have to two channels listed) would tell it the right
hash and it would fetch that from the server. I dunno know how to by-pass
that and directly fetch any particular build from hydra. Could you please
elaborate on this or refer to the documentation where it is described in
more detail.
Thanks,
Rohit
