Bug#381104: not limited only to qemu and slow machines
My laptop is fairly fast, but I can still reproduce this bug easily
enough, by booting it with a DVD in the drive. When the initramfs first
runs udev to prior to mounting the root filesystem, it scans all drives
including the DVD drive, this involves spinning up the DVD, and my
laptop's DVD drive is not very fast to spin up, it apparently exceeds
the 15 second window, and usplash drops to text mode.
There are probably also many init scripts that can take longer than 15
seconds between displaying anything. DNS timeouts come to mind. Relying
on a 15 second timeout, or any kind of timeout, seems very fragile, and
prone to producing very startling behavior to users.
