Description of problem: release notes to need mention missing /etc/modprobe.conf... before references writing or appending to it. A reference as to why it isn't created by default might make sense here as well Version-Release number of selected component (if applicable): F9 release-notes
We are using modprobe.d instead of a static modprobe.conf file. You can refer to the man page of modprobe.conf for further details. I will leave this bug report open to consider making a release note on this for the next release.
I know that *now*... but that is sort of my point. When the release notes themselves refer to writing or appending to a non-existent file, more explanation might be in order.
You can create a static file and that would just work as well. By default, there is no file necessary. So there isn't one created.
