# p17 (label: "rootfs_data") is mounted as a rootfs_data on boot instead
|

|
|
# of the loop device labeled as "rootfs_data" in p15 (label: "rootfs").
|
||
|
|
#
|
||
|

# cmdline flag is added to avoid mount "rootfs_data" partition by the
|
||
|
|
# commit 964d1e3af0e111bad6d393f8a3be702e334c2398 in fstools, but

# NCP-HG100 doesn't use it because it has a large (abount 1.6GB)

# "rootfs_data" partition and the advantage is larger than the
|
||
|
|
# disadvantages, such as overwriting the stock data in "rootfs_data"
