If you are eventually dropped to shell, you can list cmdline parameters with: cat /proc/cmdline > And after setting the file correctly, what should I run? dracut, to > build the initrd again, or grub-update, to put the options in the boot > parameter? First of all I advise to call dracut like that: dracut -H '' <kernel-version> it will generate host-specific initramfs for specified kernel version in default location. Later edit variable GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and put there parameters you want. After that regenerate grub2 config with grub2-mkconfig. I hope that helps. :-) Cheers, -- Amadeusz Żołnowski
