[CentOS] yum-cron

Hi, folks,

   Has anyone else seen the issue of having an excludes= in /etc/yum.conf,
but yum-cron appears to be ignoring it?

   This may have been the case earlier this year, where it seemed to
partly install a new kernel, then not done the post-install. I *think*
that's what I'm seeing on a box with twin Tesla cards, with yum.conf:
exclude=kernel* xorg* cuda* kmod*

and yet cron.daily reports:

/etc/cron.daily/0yum-daily.cron:

Failed to check for updates with the following error message:
Failed to build transaction: kmod-nvidia-384.90-1.el7_4.elrepo.x86_64
requires nvidia-x11-drv = 384.90
nvidia-x11-drv-384.98-1.el7.elrepo.x86_64 requires nvidia-kmod = 384.98
