Log:
modules/services/monitoring/smartd.nix: added services.smartd.devices option to
configure list of devices to monitor
By default -- if this option is unset --, all connected devices will be
monitored. Hard-coding the list of devices is worth-while, though, because this
will also configure smartd to send e-mail messages to 'root' when a test fails.
