Hi,
I usually avoid "rhgb" in the boot command as I like to see what happens. I did
this editing the /etc/default/grub and removing it and it did work for a long time.
In the last few kernel updates it did not work and rhgb is in the boot line.
I grubby-ed it away but the following update put it back. I could not find any
mention of it in /etc/default/grub or any /etc/grub config files, so where does
it come from? /boot/grub2/grub.cfg still says:
#
# It is automatically generated by grub2-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
