Like SPI and I2C, I'm against further abuse of aliases for this purpose [1].So what about the usecase for serial ports, where we use this to make sure the console come out where we want it? Is that also considered abuse or legitimate use? Note: I'm not trying to be snarky, I'm trying to understand what is the right and wrong use of alias. I'm confused about it right now :(
I guess it comes down to how ingrained the usage of any numbering is. For consoles, it was pretty important to maintain numbering and no alternative. But now with stdout-path that is less important. Perhaps if you have inittab with tty devices, then it is still needed. So I guess I would summarize the requirement to be only cases needing to maintain numbering for existing userspace. The only users really caring about this have been on N900. Rob
