BUT .. you can edit the lorax template to to use kernel-plus instead of kernel (and new repodata).. then rerun lorax to get a bootable tree and boot.iso You would then need a tree with the new kernel-plus* packages instead of the kernel-* packages This bug kind of explains the process: https://bugs.centos.org/view.php?id=13763 (look for lorax in the bug) I do want to create a process and tree somewhere for this (likely on buildlogs.centos.org). Sometime soon after I finish the i386 distro release (hopefully that is this week .. next week for some kind of bootable x86_64 Xen PV solution). The good news is, the 7.5 RHEL kernel Source RPMs should have Kevin's patch in it and it should work as released on Xen PV.
