The `status` command is the default, it displays a quick overview of all
monitored run/task/services. Here we call `initctl -p`, suitable for
scripting and documentation:

The `status` command takes an optional `NAME:ID` argument. Here we
check the status of `dropbear`, which only has one instance in this
system:
