This role is a set of tools for maintaining FreeBSD jails using ZFS. The nature of this role is to include the `tasks/jail/main.yml` with the proper variables set up. It will check if the underlying OS version in the jail is outdated, and update if necessary, while calling configured hooks during the process.
I use this on my single server box to maintain separation between various services. Of course, the nature of Ansible does make this rule and anything that uses it, scalable.
