System Ops

Operations for managing a running cache22 system: switching variants, monitoring boot health, backing up and restoring, and recovering from a broken install.

Pages in this section:

  1. Variant Switching. cache22-rebase for switching between variants or pinning to specific image refs.
  2. Health Checks. cache22-healthcheck and the auto-rollback mechanism after failed boots.
  3. Repair. cache22-repair from the live ISO when the installed system will not boot.
  4. Backup and Restore. cache22-backup for a small user-layer backup or a whole-system btrfs clone, and restoring either onto a fresh install.
