I know that GRUB kernel boot parameters, for example
panic=-1 can be added by
sudo nano /etc/default/grub and then
My application comes with a
setup.sh shell script that sets everything up for the user, as I want it to be able to be used by the non-technically minded user. Anyway, a driver called
intel_pstate makes my app not work, so on devices where
intel_pstate is detected, I want the
setup.sh file to add
intel_pstate=disable to the kernel boot parameters/boot line.
I really don't want to have to tell users to edit the boot parameters themselves, and am looking for a way to, in shell script code, add
intel_pstate=disable to the boot parameters while maintaining the existing boot parameters.
What I've already tried
- Use this code (in a sudo bash shell):
cat /etc/default/grub > grub_bkp echo "intel_pstate=disable" >> grub_bkp echo gurb_bkp > /etc/default/grub
- This doesn't work, take the following /etc/default/grub file for example:
GRUB_OTHER_STUFF=1 ... GRUB_CMDLINE_LINUX_DEFAULT='panic=-1 init=/my/cool/file.sh'
- After my script is done with it, it will look like the following, not successfully applying the kernel boot parameter:
GRUB_OTHER_STUFF=1 ... GRUB_CMDLINE_LINUX_DEFAULT='panic=-1 init=/my/cool/file.sh' intel_pstate=disable
Thank you so much for your help! :)
