Right; there was some discussion about this. A few alternatives were
suggested like

- udev scripts to create symlinks from ports to function, like:

/dev/vcon3 -> /dev/virtio-console/clipboard

- Some fqdn-like hierarchy, like

/dev/virtio-console/com/redhat/clipboard

which again can be created by udev scripts
And I dislike all of them. What I'd rather have is these devices exposed as tty's with a sys attribute that exposed the name of the device.

A sysfs attribute can even be exposed with a char device.

I didn't want to venture more into tty after the hvc thing and the
unexpected bugs that crept up (memory corruption, which is now fixed in
linux-next). I'd rather just keep it limited to the subsystems I know.

I don't think that's a good justification.

This device is very much a serial port. I don't see any reason not to treat it like one.
