From: "Aneesh Kumar K.V" <redacted> ext2 file system was by default ignoring errors and continuing. This is not a good default as continuing on error could lead to file system corruption. Change the default to mark the file system readonly. Debian and ubuntu already does this as the default in their fstab.
