Linux – How to add home-manager to the configuration.nix

linuxnixnixos

I want to add the home-manager channel to my configuration.nix, then install home-manager

I don't have experience with NixOS. A simple code snippet is much appreciated, if possible.

There is a good article about that in the NixOs Wiki. Basically, you need to import two things in your configuration.nix:

The resources from the home-manager's GitHub repository
Your own home.nix config (see the README on GitHub for examples)

imports = [
    ...
    (import "${builtins.fetchTarball https://github.com/rycee/home-manager/archive/master.tar.gz}/nixos")
    /path/to/home.nix
  ];

You might also need to add home-manager to your list of packages to be installed.

How to make a self-signed certificate persist in nixos

You didn't specify what certfile looks like in the first line. If it's a variable thats populated with a builtins.readFile, you can skip that step and just populate the variable yourself.

$> nixos-option security.pki.certificates
Value:
[ "-----BEGIN CERTIFICATE-----
... edited for brevity .... " ]

Default:
[ ]

Example:
[ "NixOS.org\n=========\n-----BEGIN CERTIFICATE-----\nMIIGUDCCBTigAwIBAgIDD8KWMA0GCSqGSIb3DQEBBQUAMIGMMQswCQYDVQQGEwJJ\nTDEWMBQGA1UEChMNU3RhcnRDb20gTHRkLjErMCkGA1UECxMiU2VjdXJlIERpZ2l0\n...\n-----END CERTIFICATE-----\n" ]

Description:

A list of trusted root certificates in PEM format.

Declared by:
  "/etc/nixos/nixpkgs/nixos/modules/security/ca.nix"

Defined by:
  "/etc/nixos/user.nix

So, setting security.pki.certificates [ "insert certificate here" ]; would eliminate the file dependency and then the configuration is self contained.

Otherwise, if you wanted to keep the content out of the configuration, you'd need to create packaging/a derivation for it and add it to the store.

How to find out which (not installed) package a file belongs to on NixOS

nix-index is what you need.

Install and build the index:

nix-env -iA nixos.nix-index
nix-index

Locate libgtk-x11-2.0.so.0:

nix-locate -w libgtk-x11-2.0.so.0

Output:

(zed.out)                                             0 s /nix/store/bc4mngklj2j7hmm21jra4641x4pm9r8z-node-webkit-env/lib/libgtk-x11-2.0.so.0
(thrust.out)                                          0 s /nix/store/wzg0k4i2cy0qsm3hwxlywxxbga019hbq-env-thrust/lib/libgtk-x11-2.0.so.0
(nwjs_0_12.out)                                       0 s /nix/store/js6klvzjfi5q4djmwb0bqzfb4x0vzm6g-nwjs-env/lib/libgtk-x11-2.0.so.0
(node_webkit_0_11.out)                                0 s /nix/store/30vm6a7bmc56ckl575rqassw60ccxjpg-node-webkit-env/lib/libgtk-x11-2.0.so.0
(mumble_overlay.out)                                  0 s /nix/store/wayx023w1nslqg2z0c5v4n0b4jxn5n06-gtk+-2.24.31/lib/libgtk-x11-2.0.so.0
gnome2.gtk.out                                        0 s /nix/store/3iqchhncghm5s458lzy99c3prfymrnp2-gtk+-2.24.31/lib/libgtk-x11-2.0.so.0

The last line says that package gtk+-2.24.31 with attribute path gnome2.gtk contains this file.
