Seems like I don’t know how to add to the kernel command line. I tried it as described in How to add custom kernel options in v4.1? - #4 by bungali
But after rebooting nothing changes in /proc/cmdline. Not sure what I’m doing wrong.
output of what I did for reference :
[FBO@dom0 ~]$ sudo vim /etc/default/grub
[FBO@dom0 ~]$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg
