For new installs, I guess it would be fine, but for existing installs they
would have to script out the changes to /etc/default/grub, and/or however
systemd-boot handles default kernel command line arguments during the upgrade

I couldn't get ttynull to be selected by default without the command line
without the console=ttynull, even when building it into the kernel (not as a
module) without the modification to printk.c
