Public bug reported:
Binary package hint: initramfs-tools
In scripts/init-top/framebuffer we have this code:
if [ -n "${FB}" ]; then
# Some framebuffer devices need character devices :-/
udevadm settle
MODPROBE_OPTIONS=-q modprobe ${FB} ${OPTS}
# Wait for the framebuffer devices to be ready
udevadm settle
else
# If we have no graphics devices yet, wait for udev to settle
[ -d /sys/class/graphics/fbcon ] || udevadm settle
[ -d /sys/class/graphics/fb0 ] || udevadm settle
[ -d /sys/class/drm/card0 ] || udevadm settle
fi
The else clause here appears to be called even on a headless system,
which would presumably cause us to call 'udevadm settle' 3 times. Sure,
it should be fast (unless there's a bug, which in my case there is), but
not as fast as just calling it once. Since I don't see any functional
value in calling it each time, I propose we consolidate to one.
