lbu command [arguments]

lbu (Local Backup Utility) manages APK overlay files on diskless Alpine Linux systems. In diskless mode, the root filesystem runs from RAM, and lbu saves configuration changes to persistent storage.
By default, only /etc is included in the overlay. Other files can be manually included. Changes are not persistent until committed with lbu commit.

Specific to Alpine Linux diskless installations. Changes in RAM are lost on reboot if not committed. Overlay storage must be properly configured.

lbu is part of Alpine Linux's approach to running diskless systems, allowing customizations to be preserved across reboots while keeping the base system read-only.
