Hello,

I tried setting the value with/without brackets and encountered the
following error:

Invalid output terminal "ttyS0"

As far as I know I can check the kernel boot parameters this way:

cat /proc/cmdline
root=/dev/vda console=ttyS0 selinux=0

The line above is same all of the time, even if I applied some new changes
to the GRUB config.
