[unused]

The hostname here defaults to the current hostname. If selecting something different it will replace the current entry in the inventory file rather than appending. No need to add the localhost, ansible adds that automatically. Rerunning the make rule to change the hostname will replace the existing entry, it won’t append

# host_vars/localhost.yml
users:
root:

The localhost file is only created if it doesnt exist. Subsequent runs of this rule will no longer modify this file so changes can be made to it if necessary

# host_vars/kelso.localhost/vars.yml
ansible_connection: local

This vars file is created in a directory named after the specified hostname. This is recreated from scratch if the command is rerun with the same hostname. Don’t add to or edit anything in this file as it will be overwritten if the command is re-reun. You can however add vars that won’t be lost by creating new yaml files in this directory. Those will never be overwritten. If make thiscomputer is run again with a different hostname, this directory will continue to exist but will no longer be used or referenced.
