An easier way of achieving this is `chattr +i`:

       A file with the 'i' attribute cannot be modified: it cannot be  deleted
       or  renamed,  no  link  can  be created to this file and no data can be
       written to the file.  Only the superuser or a  process  possessing  the
       CAP_LINUX_IMMUTABLE capability can set or clear this attribute.

Yup.  Don't trust software with your only copy of any important data!
