add selinux=0 on all of the kernel lines in grub.conf...I believe this disables it completely...and cannot be turned back on without removing that line and rebooting...obviously if you want to enable it and got back and use it again relabeling would need to be done. On Sun, Dec 22, 2013 at 8:55 AM

A guess is that the /boot that is booting the machine is not the same /boot is the current booted OS has mounted at /boot. So all updates are being put on a /boot that is not being used to boot the machine, and you need to find the actual /boot that is booting the machine and then do a dnf reinsta

To have a stuck kernel version, then what you have mounted at /boot is not what is booting your machine. You need to find the real /boot where ever it is hiding and mount it at /boot (and update /etc/fstab) and then do a "dnf reinstall" on each of the kernels you want to work, and then reboot maki
