Fortunately, I was logging the serial console (I use screen and turn on logging), and see:
/usr/lib/kernel/install.d/51-dracut-rescue.install: line 59: /boot/loader/entrie s/82bd824c4a564768ba015297f0bec908-0-rescue.conf: No such file or directory warning: %posttrans(kernel-core-4.2.0-0.rc2.git0.1.centos.el7.armv7hl) scriptlet failed, exit status 1 Non-fatal POSTTRANS scriptlet failure in rpm package kernel-core-4.2.0-0.rc2.git 0.1.centos.el7.armv7hl
You will have to generate the initrd manually using dracut.
What I see in the log from the reboot is:
Scanning mmc 0:1... Found /extlinux/extlinux.conf Retrieving file: /extlinux/extlinux.conf Starting kernel ...
====================
So please tell me how to get my Cubietruck to boot into the newer kernel.
Edit /boot/extlinux/extlinux.conf and add a entry for the new kernel.
The rbfkernelup.py yum plugin in RBF is meant for this purpose. For the Cubietruck, it will add an entry to /boot/extlinux/extlinux.conf.
You can read more about it in the section "Usage of yumplugins/rbfkernelup.py" in the README https://github.com/mndar/rbf/blob/master/README.md and in https://github.com/mndar/rbf/blob/master/doc/KERNELUP_README.md
