[grub2]How to add kernel boot options (e.g. nohz=off) ???

[RodGer GR]

Using grub legacy, adding a kernel boot option was as simple as editing the respective kernel's line in the menu.lst file.

Using grub2, how can I add a kernel boot option?
Thanks in advance for any hint.

Edit the /etc/default/grub file and add the kernel parameter to the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" line, then run:

sudo update-grub

Thanks a lot. Is there a way to add a kernel parameter which will not be default for all the linux systems available but only for those selected.
