Trying to start the vault server following the guides that specify creating the data directory in /home/vault/data results in the above error and service cannot be started.
According to the guide here: https://learn.hashicorp.com/tutorials/vault/raft-deployment-guide?in=vault/day-one-raft, changing the data directory to /opt/raft and the hcl file to reflect that the server can be started without any errors.
Trying to follow along the example in the Exoscale article about creating custom templates, you get the error about exoscale-import not found, when you are trying to validate the packer template.
Make sure that you use a current packer installation as the exoscale-import was not supported in the older versions.
