The group variables originally in ansible/group_vars/ were playbook
group variables, due to being adjacent to the playbooks. Typically they
provided default values for global variables in the all group, as well
as some more specific groups. This has worked fairly well, but results
in (at least) a couple of problems.
1. The default variable precedence rules mean that these playbook group
variables have a higher precedence than inventory group variables
(for a given group). This can make it challenging to override
playbook group variables in the inventory in Kayobe configuration.
2. Any playbook run by Kayobe must be in the same directory as the
playbook group variables in order to use them. Given that they
include variables required for connectivity such as ansible_host and
ansible_user, this is quite critical. For Kayobe custom playbooks, we
work around this by symlinking to the group_vars directory from the
directory containing the custom playbook. This is not an elegant
workaround, and has assumptions about the relative paths of the
Kayobe configuration and virtual environment in which Kayobe is
installed.
