What about changing the os-prober default to disable the debug output ?
In that way we don't need to patch grub, just do this to enable it.
export OS_PROBER_ENABLE_DEBUG=y; grub-mkconfig
Btw, the intention of using /etc/default/grub is to make the change
persistent to os-prober as it has no settings for that, and is in a
documented way. I'm fine doing it either way, because the thing here is
to suppress os-prober debug output as default, and re-enable it by
settings or command line interface are all viable imho.
Thanks,
