openmediavault-writecache

OverlayFS-based write reduction plugin for openmediavault 7

Highlights

  • Uses tmpfs + overlayfs for selected write-heavy system paths (e.g., /var/log, APT cache).
  • Safe defaults: caches dropped at reboot; optional flush on shutdown & daily timer.
  • Journald Storage=volatile option to keep logs in RAM.
  • Salt-managed config at /etc/omv-writecache/config.yaml.
  • Systemd oneshot units for mount/flush.
  • Minimal web UI (Workbench YAML) under Services → Write Cache.
