I've seen no major problems so far, having updated a fair few machines. jh _______________________________________________ John, The machine that had the boot problem related to 7.4 would only boot with the use of kernel-3.10.0-514.26.2.el7, when I used yum after booting to the 7.3 kernel and I tried to remove kernel-3.10.0-693.2.2.el7.x86_64 using the command that you recorded above, yum presented me with a list of all the kernels instead of the just the singular kernel-3.10.0-693.2.2.el7.x86_64; I was surprised and aborted the process.
