Profile

Reclaim 130GB in GitHub Actions runners for Nix buildsI created this GitHub Action to solve a persistent problem: building complex NixOS configurations in GitHub CI fails with "no space left on device" errors. Standard GitHub runners have ~20GB of free space, but sophisticated NixOS workstation or server configurations can consume 10-15GB, leaving little headroom.Nothing but Nix uses a two-stage approach:1. It creates a large BTRFS volume from unused space on `/mnt` (giving ~65GB immediately)2. It starts a background process that reclaims space by removing unnecessary pre-installed software, growing the volume to ~130GBThe technical implementation uses loop devices with sparse files and care

The company sits in the show hn launch segment, where it competes on its core product or service.

The company is listed at the Show HN launch stage of development.
