I’m not a fan of automatic updates, I love to see what I apply, mainly because I want to be able to debug my problems. But I admit sometime when you want to speed up your dnf/yum update, if all rpms have been downloaded before… it is faster.
So in /etc/cron.d/DnfDownloadOnly I have something like that * 20 * * * root dnf update -y --downloadonly
All my rpms are downloaded for a future installation, for Centos you won’t save a lot of time, but for Fedora with about 500MB of updates by week, it is a game changer
Now I’m listening you if you think yum-cron is valuable, or if you have experiences on it.
Fun, I got my tricks since a long time, and recently I installed a fedora25 for my wife (exit the last window of the house) but I needed this cron to download the updates. Of course Gnome refresh the metadata and notify the updates, but it doesn’t download the updates.
As ever, I can be wrong, so if you have pointer, I’m interested
