Description Ishan Kulkarni 2018-11-28 14:20:58 UTC
Description of problem:

If kernel command line parameters are added to "/etc/default/grub" and if the grub is rebuilt using grub2-mkconfig -o /boot/grub2/grub.cfg, it will never come into effect and will always fail.

Version-Release number of selected component (if applicable):

Observed on     :  RHEL 8.0 beta
Kernel version  :  4.18.0-32.el8.x86_64
Grub2 version   :  grub2-pc-2.02-57.el8.x86_64

How reproducible:

This issue can always be reproduced with 100% success rate.

Steps to Reproduce:
1. Fresh install RHEL 8 beta
2. Once the installation gets complete, edit "/etc/default/grub" and add kernel commandline parameters at "GRUB_CMDLINE_LINUX" line.
3. Rebuild the grub using grub2-mkconfig -o /boot/grub2/grub.cfg
4. Reboot the server and test.

Actual results:

The added parameters will never come into effect and the addition of parameters will always fail.

Expected results:

Added kernel command line parameters should work and they should come into effect.
