Here's an interesting detail: The flake name ("myNixos" in the video) can be omitted if it matches the hostname. So if you're deploying to a machine named "nixos", naming the flake "nixos" allows you to simply run: sudo nixos-rebuild switch --flake ~/mysystem
this channel is underrated as hell, you really deserve a lot more. Your vids are just perfect, they're short, concise, simple and really easy to understand. I love all of this. I was trying to use a dude's flake to copy his hyprland configuration but i couldn't understand wtf was going on, now i took a look at your vids and I'm already on a good spot. Love your vids so much, keep it on
@@vimjoyer looking forward to that! That would be a nice conclusion to the series. Suggesting on how to organize everything with different modules and for different hosts
I found your account a week ago. Now every system I work in is nix based and I'm using vim. WTF did you do to me? You are exactly the hero we need right now to help save us from those who shall not be named.
I know I just commented on another video about getting unfree stuff working. This video actually solved that! Thanks! Question: What benefits do you gain by moving the entire configuration.nix to a flake?
Where do you recommend storing your Nixos configuration as a flake? It’s my understanding that once it’s a flake you can technically put it anywhere (ie, somewhere where your used as write permissions for convenience) however, it seems like this isn’t super helpful when it comes to setting up new systems where you needs to run your configuration in order to get your user account
I have it in my home directory. You can set the flake path when rebuilding, so there's no issue on any new systems. And I usually install regular NixOS config as a first generation just to be sure that everything works.
@@vimjoyer ah gotcha. So you’re using whatever the default is that nixos ships with to get things running- specifically a user account. And then running your actual nixos config flake from your home directory to make further tweaks, add permissions to that user, and whatever else.
@@aleclowry7654 Yes, my setup is not completely declarative. If you really want, you can build your own NixOS ISO with your config. It's just not really worth it for most. Thanks for kind words!
Sure, just include another git revision in inputs, and then pass it to outputs. soemthing like: myWineNixpks.url = "github:nixos/nixpkgs/42245guehd5253..." Pass it to outputs, and then to your configuration.nix. I'll probably do a more in-depth tutorial on this in the future.
two problems i ran into, maybe this helps somebody: - If you are using a flake.nix from git-repo you should beforehand use "nix flake init", otherwise it will only opens the man page of nixos if you try to build your flake - If your flake.nix is in a git-repo, stage your files first ("git add ."), otherwise it won't build either
@@vimjoyer Oh, then i overheard that. Maybe some others are deaf like me :) And thank you for your superb nixOS videos. I'm just at the beginning of my nixOS journey but your videos are tremendously helpful!
So there is no reason to move the configuration into flake now as you just imported it into a flake. Maybe when flakes will be the default standard in 20 years more or less.
Well, that's the point. To move the configuration into a flake you just import it. You don't even have to change anything, but still get all the benefits.
@@vimjoyer Yeah but I don't see any benefits, in main configuration you already specify the channel. I love you video don't get me wrong I just want to know the benefits for now :) Thank you very much
@@BartekBroniszewski By default, you don't specify the channel in main configuration. If you mean the system.stateversion, it is not your channel, but the version of your system when you originally installed it, and it should not be changed. You could manually import needed channel without flakes, but it would be quie a lot of unnecessary work. Thanks for your comments anyway!
биг сэнкс фром май харт 😄 after `nixos-rebuild switch --flake .` it started downloading all 5Gb of system packages from scratch. It should be like this or I screwed up something?
Great video! Please build a community discord, would be lovely. I want to switch to Nix flakes but I keep getting lost, would be nice being able to chat with people about it
In the file at 1:01, shouldn't `nixpkgs.lib.nixosSystem` be `pkgs.lib.nixosSystem`? Otherwise, the variable `pkgs` which is defined in the `let` block is never used.

You popped out from nowhere, your videos are concise and your channel has a based name. Thanks for the content and keep going!
Based? Based on what?

Hey! Thanks for continuing the series!
Do you have your dotfiles published anywhere by chance?
No, not yet. I've had them public before with a link on reddit, but it was a mess. Maybe I'll clean them up a little, and review later.

Welcome to -the cult- nixos!
Hey, lots of thanks for these tutorials, they help a lot and due to the mere existance of them I'm installing nix
This is my reason too.
I know I just commented on another video about getting unfree stuff working. This video actually solved that! Thanks!
Question: What benefits do you gain by moving the entire configuration.nix to a flake?
You get version locking with flake.lock, and nice dependency management with flake inputs. Also access to new nix commands
After moving the configuration to your home directory, do you go back and delete the original config in /etc/nixos?
Sure
Thank you for this I wanted this after the last video

Can I use this to pin a specific application to a version, while being able to keep updating others? Something like Wine for example
Sure, just include another git revision in inputs, and then pass it to outputs.
soemthing like:
myWineNixpks.url = "github:nixos/nixpkgs/42245guehd5253..."
Pass it to outputs, and then to your configuration.nix.
I'll probably do a more in-depth tutorial on this in the future.
@@vimjoyer Alright, thank you!
Thank you for the video! Do you also plan on doing one about home-manager?
Of course!
Where i can look your color theme, it's so beautiful...I want the same thing, It's not just a gruvbox, is it?
It is
How did you apply dark theme to the nixos wiki page?
I installed the night eye plugin to firefox. How could I miss that one?
What are the reasons to do this? What are you gaining from moving it to a flake?
th-cam.com/video/S3VBi6kHw5c/w-d-xo.html
For some reason this video is missing from the NixOS playlist. Had me really confused since yesterday.
Forgot to add it, thanks!
Short and sweet how you like them ! 🍪

Yep, I mentioned the git repo thing in the "flakes explained" video. As for the first problem, I'm not sure, never had it.
@@vimjoyer Oh, then i overheard that. Maybe some others are deaf like me :)

do you have plans to share dottfiles or similar
Yes, later
Thank You!

Hi, there will be more videos on Nixos?
Sure will, I was just quite busy this week. Thanks for asking!
Are you switching over to nix?
I've been using it on all machines for 6 months now
биг сэнкс фром май харт 😄
after `nixos-rebuild switch --flake .` it started downloading all 5Gb of system packages from scratch. It should be like this or I screwed up something?
Yeah, that is fine, flake probably has a different nixpkgs version. Ю ар Велком.
@@vimjoyer exactly! nixos-unstable vs nixos-23.05 in default configuration
Great video! Please build a community discord, would be lovely. I want to switch to Nix flakes but I keep getting lost, would be nice being able to chat with people about it
We have a discord, check last video's description
In the file at 1:01, shouldn't `nixpkgs.lib.nixosSystem` be `pkgs.lib.nixosSystem`? Otherwise, the variable `pkgs` which is defined in the `let` block is never used.
It is supposed to be `nixpkgs.lib.nixosSystem`, but you are right, pkgs is redundant in this case
Great video!
