If you're going to take that approach, you might find chattr +i useful.
man chattr says:
       A file with the ā€˜iā€™ 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.

So you would have to explicitly use chattr -i to modify it.
