# rds-datadir — boot oneshot that discovers the hot-plugged data volume, formats
# it if authorized, and mounts it at the datadir mount point. It runs after the
# agent has written the authenticated handoff and before anything can use the
# PostgreSQL datadir. Soft ordering keeps a failed boot visible on the console.
