Why does /dev include devices that do not exist?
Wouldn't it be friendlier to only list existing devices?
Or am I missing something obvious?

/dev is only a bunch of device nodes that knows nothing about any
devices physically present in the system.
devfs creates a dynamic filesystem that is managed by the kernel that
only shows the devices present in the kernel at that point in time.
udev attempts to manage a /dev partition from userspace by watching all
of the hotplug events coming from the kernel that announce device
removal and additions.
Hope this helps,

Yeah, I finally figured that out. For some reason, I'd missed that item...
...as it is, I think I'll spend some time reading the Documentation
folder. Those text files must be there for some good reason... ;)
