  # TREK is a single-writer SQLite app on a ReadWriteOnce PVC, so the default
  # RollingUpdate would start a second pod holding the same volume before the old one
  # exits — a Multi-Attach deadlock, or two processes on one travel.db. Recreate tears
  # the old pod down first. Keep it, see updateStrategy in values.yaml.
