Usage: Add the kosmos_encfs::default recipe to the run list of a node. Creating the encrypted directory will keep it mounted. After a reboot, start the encfs service and enter the password: ``` $ systemctl start encfs encfs password: ``` For now postgresql@12-main is a hardcoded dependency of the encfs Systemd unit that is automatically started once the user inputs the correct password. This list of dependency will need to be different for every server, based on the services it is running
