freebsd-update.conf IgnorePaths linker.hints not working

[Gregory Orange]

Hi everyone,

I've got freebsd-update cron running every night, and each time get the 
following (regardless of whether I then run freebsd-update install):
----
The following files will be updated as part of updating to 8.4-RELEASE-p10:
/boot/kernel/linker.hints
----
I've found a few discussion threads suggesting changes to 
freebsd-update.conf being advisable, so I've done that, to no avail. 
Also following these instructions for rc.conf:

No luck. I still get the message at every run. My freebsd-update.conf 
has no other changes:

Can anyone suggest how should I resolve this?

TIA,
Greg.
