so as I understand, `update-grub` utility generate entries in a way to
perform a quiet boot using `GRUB_CMDLINE_LINUX_DEFAULT` parameter.
do you think if it's possible to perform these changes manually to menu
entries? 

I also find that we can redirect kernel logs to a separated TTY using 
`GRUB_CMDLINE_LINUX="console=tty...`. I assume this parameter is also
processed by `update-grub` utility. is it possible to perform same
action using `kernel-arguments` or some other modification in menu
entries?
