What's with the '.'?  009 will be the next release, hopefully soon, I'm
waiting on some stuff from the libsysfs authors...

pty and pts are handled by the devpts filesystem.
For raw devices I have a patch floating around in my kernel tree that
needs to be looked at a bunch.  Care to test it out?

Again, I have patches, but don't think they are ready for prime time.  I
want to get these out soon, need to stop answering dumb devfs vs udev
questions on lkml...

For scsi cdroms it's easy, look at the type file in sysfs.  For ide
cdroms, code needs to be added to the kernel to export that information
for you to determine this.

Good point, I'll go change that.
