# Install scripts using Nix to achieve cross-distros
- This directory is currently WIP.
- See also [Install scripts | illogical-impulse](https://ii.clsty.link/en/dev/inst-script/)
- See also [#1061](https://github.com/end-4/dots-hyprland/issues/1061)
**NOTE: The sdata/dist-nix is not for NixOS but every distro, using Nix and home-manager.**
## plan
Note that this script must be idempotent.
TODO:
- [ ] Write a proper `flake.nix` and `home.nix` and other files under `dist-nix/home-manager/` to install all dependencies that `dist-arch/` does. (**excluding** the screenlock)
## Attentions
### PAM
On non-NixOS distros, programs using PAM (typically screen locker) will not work if installed via Nix, so user has to use their own distro's package for the screen lock.
- One problem is that Debian(-based) distros use modified version of PAM which supports `@include` directive in `/etc/pam.d` config files but the PAM from Nix does not support it, see [this comment](https://github.com/NixOS/nixpkgs/issues/128523#issuecomment-1086106614).
- Another problem is the location of a suid helper binary that is necessary, see [this comment](https://github.com/end-4/dots-hyprland/issues/1061#issuecomment-3403195230).
The problem could be solved by using the system-provided libpam instead.

### NixGL
On non-NixOS distros, packages installed via home-manager have problem accessing GPU, especially Hyprland because it requires GPU acceleration to launch. `nixGL` should be used to address the problem.
