Summary0007420: Kernel 3.10.0-123.el7.x86_64 doesn't include options in /etc/default/grub
DescriptionFor reasons that are not of any importance to this particular issue, I need to disable selinux, and have a bootable system.

With centos7, this requires adding a boot option flag (selinux=0) to the kernel command line.

To make this change permanent, and added it to the GRUB_CMDLINE_LINUX variable in /etc/default/grub. I confirmed that my changes are included in the resulting grub2-mkconfig output.

The problem is when I updated to kernel 3.10.0-123.el7.x86_64 (and possibly other updates, I haven't been running centos 7 very long), it completely ignored my changes in /etc/default/grub.

This resulted in a non-bootable system.

It's bad enough that systemd refuses to boot without selinux, but even worse that the mechanism to make such a change permanent is ignored by kernel update RPMS.
Steps To Reproduce1.Change the GRUB_CMDLINE_LINUX options in /etc/default/grug
2. Use yum to install updated kernel RPM
