[$] Hiding the Fedora boot menu

The venerable Linux boot menu has made its appearance at boot time sincethe days when LILO was thestandard boot loader, through the days of GRUB, and onward totoday's GRUB 2and others.It is sometimes configured out by distributions as something that willpotentially confuse less-technical users, but it has been a mainstay ofFedora for many releases. A recent proposalto hide the menu, starting in Fedora 29, has met a mixed reaction, butthose who are not in favor are also those most able to revert to theexisting behavior.
