Let me give an example. Hotplug will automatically load the ALSA drivers for my sound card, and /dev/snd/* are created (by devfs or udev, it doesn't matter for now). Suppose that, some time, I run a program that tries to use OSS for sound. Now, the ALSA OSS emulation is not loaded by hotplug, and I don't want it to. It's nice to have snd-pcm-oss automatically loaded when some legacy application tries to use /dev/dsp.
