The thing I'm now trying to do is automate the cleaning out of things left behind by akmod(?) after the weekly patch (dnf upgrade). A cron job seems like the most natural way to do this. Since the patches are weekly, I believe the cron job should be weekly, scheduled for a day and time when the workstation is almost always up, but idling.

FWIW, once you've deleted all the files in /var/cache/akmods/nvidia only 2 files will be created when a new kernel is installed. The log and the rpm. They will total approx 12.5MB. A rather tiny amount to fret over, IMO. But, if you are concerned you're going to forget about this and need to automate it. OK. Just know that even if you do forget it will take about 84,000 new kernels before 1GB is used. The easiest way to automate this is to place the "script" which deletes the files in that directory in a file in /etc/cron.weekly maybe calling it 98-akmod-clean and having its ownership root:root and executable. -- The key to getting good answers is to ask good questions. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
