  34 # After the commit bad1835f27ec31dbc30060b03cc714212275168a in fstools,
  35 # p17 (label: "rootfs_data") is mounted as a rootfs_data on boot instead
  36 # of the loop device labeled as "rootfs_data" in p15 (label: "rootfs").
  37 #
  38 # cmdline flag is added to avoid mount "rootfs_data" partition by the
  39 # commit 964d1e3af0e111bad6d393f8a3be702e334c2398 in fstools, but
  40 # NCP-HG100 doesn't use it because it has a large (abount 1.6GB)
  41 # "rootfs_data" partition and the advantage is larger than the
  42 # disadvantages, such as overwriting the stock data in "rootfs_data"
  43 # partition.
