With, I believe F11, the bootup displays are controlled via Plymouth as specified on the kernel boot line. Have a look at https://fedoraproject.org/wiki/Features/BetterStartup. I'll leave it to you to find the Plymouth documentation. :-) Basically, "rhgb" means "Red Hat Graphical Boot". Prior to Plymouth all boot messages would be presented in graphical mode with it on the kernel line. If not there, it will be text. With rhgb and quiet defined you wouldn't see any boot process messages unless an error occurs. FWIW, I don't know how, with Plymouth, to get the display process to show boot messages in graphics mode when no errors exist. To boot, pun intended, I just started an F11 instance of a VM with the network card disconnected and while I expected to see the "FAILED" when the network attempted to start that did not happen either. (I may have to learn more about Plymouth to decide if that is a bug). As for you last question... Are you saying that you see it counting down from 3~0 or 5~0 but in 2 seconds? I have seen it when I only catch the countdown from 3~0 but that is a function of my monitor being slow to respond. -- It's multiple choice time...
