I don't understand why yum doesn't want to install updates when a new kernel is available:
sudo yum update ... ---> Package kernel.x86_64 0:3.16.7-200.fc20 will be installed ... [nothing about kmod-nvidia-blah]
** yum wants to update kernel **
rpm -qa kmod-nvidia* kmod-nvidia-304xx-3.16.6-203.fc20.x86_64-304.123-1.fc20.16.x86_64
** kmod-nvidia 3.16.6-203 is already installed **
yum info kmod-nvidia* ... Name : kmod-nvidia-304xx-3.16.7-200.fc20.x86_64 Arch : x86_64 Version : 304.123 Release : 1.fc20.17
** OK, there it is! The kmod I need for the new kernel. So why doesn't yum want to install it?
