|Summary||0007420: Kernel 3.10.0-123.el7.x86_64 doesn't include options in /etc/default/grub|
|Description||For 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 Reproduce||1.Change the GRUB_CMDLINE_LINUX options in /etc/default/grug|
2. Use yum to install updated kernel RPM
