Error: Symlink from modules failed

I have this error:

retrieve_conf failed to sym link:
/etc/asterisk/sip_notify.conf from core/etc (Already exists, not a link)
This can result in FATAL failures to your PBX. If the target file exists and not identical, the symlink will not occur and you should rename the target file to allow the automatic sym link to occur and remove this error, unless this is an intentional customization.

(retrieve_conf.SYMLINK)

Is this something to worry about?

The system seems to be running fine.

Thanks.

Renamed the file and reran config update and the error is gone.
