#TODO: Add 'check' as fs_mgr_flags with data partition.
# Currently we dont have e2fsck compiled. So fs check would failed.

     The line: /dev/block/mmcblk1p2 /system ext4 ro,barrier=1 wait is for mounting the 2nd parition of sdcard as system
     The line: /dev/block/mmcblk0p3 /data ext4 nosuid,nodev,barrier=1,noauto_da_alloc,discard wait,check,encryptable=footer is for mounting the 2nd parition of sdcard as system
