32f808fcfa - Unbound exits with a fatal error when the auto-trust-anchor-file
fails to be writable.  This is seconds after startup.  You can
  load a readonly auto-trust-anchor-file with trust-anchor-file.
  The file has to be writable to notice the trust anchor change,
  without it, a trust anchor change will be unnoticed and the system
  will then become unoperable.
