we always will apply the final result just fine, when stuff stops changing. It's actually a nice feature and no a problem at all, that we only see the most recent state.

Stuff never stops changing until the machine shuts down, its undefined.

Either you don't, or you just don't want to understand what all this is about. :)

Sure, with the ioctl() we've seen many not interesting changes, but we often miss the single one that is important -- the last last one. The thing is that we don't need to sleep here and miss changes.

So we fix the ioctl interface, it's not exactly hard to do now is it.

It's a straight-forward and simple text interface that does all we need to track console and vt changes.

Except that it doesn't address things like the permissions side of things.

NAK again

Specifics please.

"We have an interface that doesn't quite work for our case and we think that is a bug" is not the reasoning behind writing a new random one with a totally disconnected permission model that doesn't work either.

Fix the one we have.

So how do you think you'll fix it? I better don't get into your ioctl() business.
