Ringtail

Service host and gaming PC. Custom-built PC running NixOS.

Specifications

Property Value
CPU AMD (desktop)
GPU NVIDIA RTX 4080 (16GB VRAM)
Storage NVMe (boot) + 3x SATA drives
OS NixOS 25.11 (Sway/Wayland)
Tailscale hostname ringtail.tail8d86e.ts.net

Software

Managed declaratively via nixos/ringtail/configuration.nix.

  • Desktop: Sway (Wayland compositor) with wezterm terminal
  • Shell: Fish (default login shell)
  • Gaming: Steam
  • Dotfiles: chezmoi (requires .chezmoiignore updates in dotfiles repo for Linux)
  • Secrets: 1Password CLI + GUI (CLI integration via desktop app biometric unlock)

Maintenance Notes

NixOS rebuild: From the blumeops repo, run mise run provision-ringtail or on ringtail directly:

sudo nixos-rebuild switch --flake /etc/nixos#ringtail

NVIDIA drivers: Uses proprietary (closed-source) drivers. The --unsupported-gpu flag is passed to sway via greetd since sway officially only supports open-source drivers.

Chezmoi: The dotfiles repo (github.com/eblume/dotfiles) is macOS-centric. A .chezmoiignore needs to be added to skip macOS-only files on Linux (Brewfile, macOS-specific PATH/SSH_AUTH_SOCK). This is tracked as a separate task outside blumeops.
