-# Only groups_vars/ and host_vars/ directory are used for setting up devices
-# and nodes.
-# > Files, files, files, ... only files, everything files!
-#
-# The main goal here is to allow flexible code reviews and edits, POSIX
-# compliant actions over files, and using "less is more" moto. Moreover, each
-# host/group/node is individually track on version control.
