Problem

Whenever we start vector on our Windows systems, the following warning message is logged:

{
  "buffer_id": "vector_gw",
  "canonicalized_data_dir": "\\\\?\\C:\\var\\lib\\vector\\buffer\\v2\\vector_gw",
  "data_dir": "/var/lib/vector\\buffer\\v2\\vector_gw",
  "host": {
    "name": "<HOST_NAME>"
  },
  "message": "Found no matching mountpoint for buffer data directory.",
  "metadata": {
    "kind": "event",
    "level": "WARN",
    "module_path": "vector::config::validation",
    "target": "vector::config::validation"
  },
  "observed_time_unix_nano": "2024-04-24T19:08:30.694024900Z",
  "pid": 11704,
  "source_type": "internal_logs",
  "timestamp": "2024-04-24T19:08:29.912690700Z"
}

Does the mount point logic work on Windows?
