    4 f2fs-tools' fsck tool by default refuses to check a mounted filesystem
    5 whether it's mounted read-only or not. This causes fsck to fail at boot
    6 and prompt for the root password for filesystem maintenance. In order to
    7 avoid this it is recommended that the 6th field (fs_passno) of any f2fs
    8 entries in /etc/fstab be set to 0.

   10 Hopefully this will be fixed upstream sometime in a new release.

   12 If you REALLY want to work around this limitation a user-submitted patch
   13 for /etc/rc can be found below, but note that this is NOT supported.
