	# Seems to be a bug in setup-nix-cache-action where, even though we're only providing a trusted_public_keys input
	# and no secret_keys input, it still tries to create a post-build-hook that will push packages to the cache. This
	# is a hacky workaround to remove that hook -- we find the post-build-hook created by setup-nix-cache-action and
	# truncate it to 0 bytes so it does nothing.
	- run: sudo find /home/runner/work/_temp -type d -name 'setup-nix-cache-action-*' -exec sh -c 'truncate -s 0 "$1"/post-build-hook' _ {} \;

	# Run all the tests, with unlimited log lines in CI
