Comment:
Maybe we should document this need in docs, but we have a clear policy of not making runtime changes to user's systems; that includes auto enabling services like firewall, same way we don't restart sshd after updates.

We can consider documenting this in void-docs or a `README.voidlinux` file for the package.
