The following files have notes in comments, advising user to edit them directly:
So these ones are definitely must be marked as %config in %files section.
This file doesn't look to me as intended to be edited by end user, however I'm not so sure. If user may edit it, then it also must be marked as %config
So the %files section should look something like this:
%ghost %config(noreplace) %verify(not md5 size mtime) /etc/modprobe.d/local.conf
Since this package was retired in favor on kmod I'm going to close this.
