Let's say I have two kernels -- the default that's maintained by the
distro, and one that I'm playing with that I compile from source to get
dpkgs. Call the distro one linux4.4 and "mine" -- linux4.16 (for
reference, all this is playing out on an ubuntu system...not sure if
that will garner me some eyerolls.... ;) ).
I'm using 4.16 to test the effects of BFQ, and 4.4 because I need a
fallback. With that in mind, I'd like to pass the kernel parameter
"elevator=bfq" to 4.16 ONLY (and not 4.4).
Does anybody know where to look to add this to /etc/default/grub.cfg
without passing the parameter to all kernels that are then found after
grub-mkconfig (which will inevitably run after a few instances of sudo
apt-get update && sudo apt-get dist-upgrade)?
