Besides the general BiBiGrid configuration there is also an ansible.cfg and a slurm.conf.
For 99% of all users those never need to be touched. However, some use cases require changes to those configurations.
For that purpose we store defaults in resources/defaults and on the first run copy copies to the actual locations
resources/playbook/ansible.cfg and resources/playbook/bibigrid/templates/slurm/slurm.j2.
That way you can make changes and if something doesn't work, you can just delete the configuration to go back to our
default one.
The slurm.j2 is not a static configuration file, but instead a jinja template for the actual configuration that is
generated during runtime. That is necessary because it contains the actual instance names that are only known at runtime.
The jinja template is converted to the actual configuration by ansible in the 042-slurm.yaml task.
The slurm.j2 also takes certain information from your BiBiGrid configuration (see slurmConf).

The ansible.cfg defines how ansible behaves during runtime. A key that sometimes need to be adapted is timeout which
is the timeout for the connection plugin. If your host answers very slowly, a low timeout might cause issues.
