# PURPOSE
|
|
# ─────────────────────────────────────────────────────────────────────────────
|
|
# Maintains the persistent partner conf backup at /boot/config/.cache/vv/d/.
|
|
# Runs every 15 minutes via SYSTEM_WATCHDOG_SCRIPTS.
|
|
#
|
|
# When remote is OFFLINE:
|
|
# Writes/refreshes partner confs from RAM cache → persistent location.
|
|
# Means if this host reboots while remote is still down, conf_cache_restore.sh
|
|
# can load the partner vars into RAM so fallback.sh has what it needs.
|
|
#
|
|
# When remote is ONLINE:
|
|
# Removes the persistent backup if present — not needed, conf_sync.sh will
|
|
# pull fresh on next boot.
|
|
#
|
|
# Silent when remote is online and no backup exists (normal state).
|
|
# No-op when FALLBACK_ENABLED=false or CONF_SYNC_ENABLED=false.
