ZFS isn't only a filesystem. It's your toolset for precise storage operations and security. You can stream datasets to new disks or even machines. In this example you will migrate a database server jail.
You don't maintain only computer systems. You maintain a biological system too - yourself. The operator. If the operator disappears - what will happen to the system?
Some prefer SaaS. Some value self-hosted. The Gitea source-code management platform is a good fit for your FreeBSD system, running in jails. It's not paranoia. It's compartmentalization.
