Hello,
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?
I know that Silverblue is a little bit different from regular Fedora in the way that booting is handled. I’m wary of using the normal Fedora docs, and was hoping to find some explicit confirmation that this approach is safe on Silverblue.
