Marco, how should init scripts that load modules and use the device
afterwards behave?, is there a common policy? My best guess is the
following, but I'd like confirmation:
if [ -x /sbin/udevsettle ]; then
/sbin/udevsettle || echo "Warning: udevsettle timeout"
if [ -e /dev/wanted_device ]; then
die "wanted_device not present in /dev"
