Re: F29 System Wide Change: Hide the grub menu

I think it was a fair question which was raised about the size 
of the audience being sought to be catered to, vs the mass of 
users of Fedoraproject code, and their 'least astonishment' 
and loss of acquired knowledge as to use

If there are, oh, say, twelve people in the world that 
actually care about instantaneous GUI boots in Fedora, it is a 
waste of time to mess with this thread


but to the most recent point raised about 'modifier keys'.  I 
recall doing this back in DOS days with a third-party tool 
that permitted 'BAT files' to query for Shift, Alt, and Ctrl 
key states, and to build boolean decision trees:

or, perhaps, better still and less complex as in needing to 
suppress a boot menu, a message at the bottom of the GUI 
screen from its first appearance and for ten seconds or so:
	Hold either Shift key for more boot options

so that a person could be habituated to holding a 'harmless' 
key. Harmless, in the sense that it does not fill and over-run 
a key-press buffer and start beeping at the holder

I speak having personal setup options of:

	15 sec timeout at the grub options menu	

	with plymouth graphical stuff, rhgb, and quiet 
		disabled

	always booting to a non-GUI console
		why: multi-user.target for something formerly
		though of as 'single user', although with 
		multiple PTYs ?? 

	with a 640x480 console

	which is NOT cleared away
	
to support the fact that I am almost always remote and on KVM 
devices of varying resolutions, and so favoring a 'least 
common denominator' as to capabilities

That last (preserving the TUI boot screen was tricky to find 
docoed

Use:
	 # systemctl edit getty@tty1

and add:

        #
        [Service]
        TTYVTDisallocate=no
        #

as the description for the service
