Very very minor but style is usually to use .with_context(|| format!(...)) to avoid string allocation even on non-error paths.

Upstream we are starting to use grub configs that are partially baked into bootupd [1] and partially baked into the image via the OS vendor (in our case a grub2/30_console.cfg file [2]). Let's look first to see if grub2/30_console.cfg exists when trying to write new console settings before falling back to grub2/grub.cfg. [1] coreos/bootupd#543 [2] coreos/fedora-coreos-config#2769
