I would like to edit some of the Grub configuration on my install of Fedora Silverblue. If I go ahead and edit
/etc/default/grub or add new files to
/etc/grub.d/, what commands do I need to make that configuration active?
Since this is Silverblue I’m aware that grubby is not safe to use. I’m also aware that for kernel arguments specifically I can use
rpm-ostree kargs. However, I’m interested in changing other bits of Grub configuration. (In case it matters I’m interested in trying different
GRUB_TERMINAL settings as currently Grub menus render very very slowly.)
So, what is the recommended way to make changes to Grub configuration and apply it in Silverblue?
