Ok, folks,

   I've identified what my problem is, trying to install the NVidia
proprietary drivers: in kernel-devel-3.10.0-514.26.2.el7.x86_64, there
is a file

   It does not exist in the kernel-devel-3.10.0-693.2.2.el7.x86_64
package. Is this something that got missed, or did HR drop it, or....?
