BFQ via grub2

Hello.
I was reading arch wiki article about repo ck kernels and decide to grab one for my k8 family processor. But theres problem that comes with idea of turning BFS via grub; it happened that i don't have menu.lst so i have no idea where to add "elevator=bfq" line.
Request step by step explanation much appreciated.

Re: BFQ via grub2

You've got "BFS" in the subject - you meant BFQ.

Just use grub.cfg (for Grub2) instead of menu.lst (for Grub1).

Don't be so helpless, we don't do step-by-step here. Read the grub wiki page, which says, among other things:

To pass custom additional arguments to the Linux image, you can set the GRUB_CMDLINE_LINUX variable in /etc/default/grub. This is analogous to adding commands to the kernel line in GRUB Legacy.

Re: BFQ via grub2

you edit

/etc/default/grub

, and then run

grub-mkconfig -o /boot/grub/grub.cfg
