Unattended reboots with encrypted disks

The blog post introduces ZKeys, a managed service designed to securely store encryption passphrases off-site, allowing for unattended reboots of home servers or NAS systems by requiring periodic keepalive messages. This ensures that if the server is stolen, the key is locked automatically, maintaining data protection. The author shares personal development experiences in creating this tool and emphasizes the importance of disk encryption for modern small servers.
