I'm trying to add a kernel option "xxx" by adding it to the existing
GRUB_CMDLINE_LINUX="xxxx crashkernel=auto rhgb quiet"
line in /etc/default/grub, but after doing so, when I run
grub2-mkconfig –o /boot/grub2/grub.cfg
it produces exactly the same grub.cfg file as before (confirmed with diff).
What am I missing?
I'm running CentOS Linux release 7.6.1810 (Core)
