Well, with the plethora of messages in the archive, if that is the only
one you find where modprobe.conf was corrupted then it does not seem
very prevalent an issue.

Personally I have never had that issue on any system I manage.

I understand your concern and am glad you had the backup, but what is
unique about your systems that made it happen to you when very few
others are reporting this problem?
Is someone interrupting the update before it completes the configuration
step?  Is there something else that interferes? such as maybe the update
running and backups starting at the same time, etc.?

Kernel updates seem to take a long time to finish the update.  At times
I have felt they were hung and have been tempted to kill the power since
the system was inaccessible at the time, ( although I never
have :-) ) .... but after waiting a long enough time they have always
finished for me.
