Input Management

Inputs are pinned with nixtamal and resolved with with-inputs. There is no flake.lock; pins live in [nix/tamal/lock.json]!(nix/tamal/lock.json).

Entry points

File	Purpose
default.nix	Primary entry point; returns full flake outputs
configuration.nix	Convenience entry point; selects the NixOS config for the current hostname (impure — reads /etc/hostname)
flake.nix	Thin shim so flake-aware tools still work

Switching

nh os switch -f ./configuration.nix

Updating inputs

nixtamal refresh             # refresh all non-frozen inputs
nixtamal refresh <name>      # refresh one input
nixtamal check-soundness     # verify all fetches resolve

See definition at [readme.nix]!(modules/meta/files/readme.nix).

Hosts

The set of NixOS hosts is defined via an option which accepts deferred modules. Differentiating the hosts as a subset of the NixOS modules allows us to map over the hosts without string matching.

See usage at [autolycus]!(modules/hosts/autolycus/default.nix).

Closure Checks

Closure size checks are defined via the closureChecks option. Each entry logs the human-readable closure size; an optional budget field causes the check to fail if the size exceeds it.

See checks at [closureChecks/]!(modules/closureChecks/).
