{option}`configurationFile` takes precedence over {option}`configuration`. | ||
Note: Restricted evaluation blocks access to paths outside the Nix store. | ||
This means detecting content changes for mutable paths (i.e. not input or content-addressed) can't be done. | ||
As a result, `nixos-rebuild` won't reload/restart the systemd unit when mutable path contents change. | ||
`systemctl restart fluent-bit.service` must be used instead. | ||
