You should be able to report that as a Bug to your distribution.

Otherwise, there are things you can try:

Remove the "w" (write) permission of the file. Maybe make it inmutable.

A cron job replaces it (don't bother with the edit).

If you are using Apparmor, you can deny the permission to 'driverless' 
for writing that particular file.
