setting boot parameters

[Member Keeely]

Hi,

I’m struggling to figure out how to set kernel boot parameters. I can see plenty of docs for how to set them on boot of the DVD, but I want to add a parameter permanently to the installed system.

I’ve found /boot/grub/grub.cfg, however that tells me not to edit it, refers me to /etc/grub.d. I’ve looked through those files but it isn’t obvious which one I should be changing. Unfortunately I’m used to LILO, which is just a single file with append= line, and this is the first time I’ve needed to do this with Grub.

thanks!

Installed antiX Linux

From https://antixlinuxfan.miraheze.org/wiki/Boot_Parameters#Adding_options_to_Boot
For most antiX Linux systems, the installation process will install GRUB (to a selected partition or to the Master boot Record) and it will use it to boot your system.

If you want to add or remove Boot Parameters but you want to test them first before making them permanent, edit them at boot in the grub selection screen.

If you want to add boot parameters and make them permanent (or you are happy with the results of testing them using the above procedure), you can edit the /etc/default/grub file and update grub.

Meaning:
1. open with root privileges /etc/default/grub.
2. Edit the line containing GRUB_CMDLINE_LINUX_DEFAULT and add the boot parameters inside the ” symbols ”
3. Save the file, close it and update grub
sudo update-grub

I hope this helps.

Are you running live?

Philosophers have interpreted the world in many ways; the point is to change it.

antiX with runit - leaner and meaner.

That’s an interesting question. I wasn’t for that, but I also want to do this after cli-installer has run, but before the first boot. I’m just trying to figure that out next.

EDIT: It does seem that editing the live file /etc/default/grub gets picked up once grub is installed as part of cli-installer, so I guess that’s the way to get an option on first boot.

If you just need to make sure its there on the first boot, on the Grub Boot screen, press e to edit the boot lines, and once done, F10 to boot

Cheers BobC. Yes, I managed to figure out that side of things (entering manually at boot time). It was the making permanent part I struggled with.
