[Nix-dev] Dynamic Nix Expression Configuration

Hello everybody, What's the best way to send configuration parameters to Nix expressions? Say I have a tool (a bash script) that dynamically generates nix expressions based on other runtime factors. I can use the sed tool to find/replace some properties inside the `x.nix` files. But this can b

[Nix-dev] GRUB Options

Hello, How would one use Nix to set GRUB options such as: ``` GRUB_CMDLINE_LINUX="clocksource=tsc" ``` Assuming that this means: "Command-line arguments to add to menu entries for the Linux kernel. " Then does that mean I can use: ``` boot.kernelParams = [ clocksource = "tsc"; ]; ``` Th

[Nix-dev] Configuring Packages installed with `nix-env` is impossible?

Hello, What does `nix-store --serve` do? I can't find any documentation on this command. I found it here: https://github.com/NixOS/nixpkgs/blob/74859a88e5ac441ec92b2d93cc78ab395eb105e8/nixos/modules/services/misc/nix-ssh-serve.nix Thanks, Roger ___ n

[Nix-dev] nix-store --query --deriver command gives the wrong derivation?

[Nix-dev] Variable Assignment in Nix Expressions

Hello, How come the nix-repl allows a freestanding variable assignment, but the actual Nix expressions don't? ``` # allowed in nix-repl but not in normal nix x = 5 ``` ``` # allowed in normal nix and nix-repl let x = 5; in {} ``` Apparently this has something to do with the purity and lambda c

Hey, Changing nixos generations won't affect the grub boot partition, that only changes which nixos kernel and initramfs image gets booted. This looks like an error in the Grub partition. Maybe you recently updated it or changed it, or the partition got corrupted. This is why other operating sys

Re: [Nix-dev] PCI Expresscard not working under NixOS

When you plug something in, the kernel log should show something. If it doesn't then the kernel doesn't know about it, nothing in the userspace can help. Make sure you're running those commands before you plug the usb in. Also I used to have faulty usb cables, but even then the kernel showed some

Re: [Nix-dev] Why having releases if you break things in it often

Hey, I'd suggest for you to not use channels. I don't. Pin your nixpkgs to a commit hash. And upgrade when you want to/need to. This should be the recommended way IMHO. On 11/02/2017 10:07 AM, "Stefan Huchler" wrote: > Hello, > > I start to get frustrated again, the documentation of nixos is not
