Linux admins, on the other hand, are used to dealing with a wide variety of interfaces and configuration elements. Depending on what needs to be configured, one package might have a smattering of different configuration files that follow a particular syntax, while a different package will have only one configuration file with a completely different configuration syntax. Changing parameters in /etc/ssh/sshd_config is nowhere close to adjusting a Postfix configuration, for instance. The only commonality is the need for a text editor like vi to make those changes. And using a text editor is much different than logging into a switch CLI and issuing commands for a live application, then saving the configuration.
