Rijan's NixOS Configuration

System Update

# Update flake lock file (nixpkgs, home-manager, etc.)
nix flake update

# Rebuild and switch
sudo nixos-rebuild switch --flake .#nixos

# Or rebuild for next boot only
sudo nixos-rebuild boot --flake .#nixos

Updating Custom Packages

Custom overlay packages (in pkgs/) have pinned versions and hashes. Use nix-update to bump them automatically.

Quick start

# Update all auto-updatable packages
./update-pkgs.sh

# Update a specific package
./update-pkgs.sh ferrite

Package update support

Package	Source	Auto-update?
ferrite	GitHub (OlaProeis/Ferrite)	✅ Fully automatic
edge-tts	GitHub (rany2/edge-tts)	✅ Fully automatic
mzmine	GitHub release (mzmine/mzmine)	⚠️ Semi-auto (uses --url hint)
google-antigravity	RPM repo (Google Artifact Registry)	✅ Auto via RPM repo metadata
plink2	S3	❌ Fully manual
snpeff	S3	❌ Fully manual

For packages marked fully manual, update version, url, and hash by hand. Use nix-prefetch-url <new-url> to compute the new hash.

One-off usage (without the script)

# Run nix-update directly
nix-update --flake ferrite

# Or without installing nix-update
nix run github:Mic92/nix-update -- --flake ferrite
