The service switch
The implementation of certain system services
such as host and user name lookup is controlled by the service switch.
The ServiceSwitchFile option points to the name of a file
that has the service definitions. Each line has the name of a service
and the possible implementations of that service. For example, the file:
hosts dns files nis
aliases files nis
to look for hosts in the Domain Name System first.
If the requested host name is not found,
it tries local files, and if that fails it tries NIS.
Similarly, when looking for aliases
it will try the local files first, followed by NIS.
