Sorry for being a little bit confused, but by virtual devices you mean things like pty's or all the other stuff we already see under /sys/device/virtual ?
I'm yet unsure what the better way is. If we're just talking about pty's specifically, I maybe could live with threating them like "special sort of pipes", but I guess that would require some extra magic.
If I'm not mistaken, the whole sysfs stuff is automatically handled device classes and bus'es - seems that tty's are also class devs.
How would you skip the virtual devices from sysfs ? Adding some filter into sysfs that looks at the device class (or some flag within it) ?
