Hi,  
In order to boot and shutdown mender image in quiet mode I added “quiet” parameter in console\_bootargs in grub.cfg file and rebooted system.  
But It doesn’t show any effect.  
I also tried “splash” parameter to display splash screen but that also not working.

Please find below code of my grub.cfg file,

mender\_grub\_storage\_device=hd0

mender\_grub\_storage\_device=hd1

@drewmoseley any idea why it is not working for me ?
