I favor none of the virtual devices showing up in sysfs. Maybe existing userspace needs the devices in sysfs, but if the solution is simply to skip sysfs for virtual devices that is much simpler.
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) ? --mtx -- --- Hinweis: unverschlüsselte E-Mails können leicht abgehört und manipuliert werden !
