It sounds like you're saying that /dev/temp might, sometimes, not be what I want to use. On a default etch install it has the same major/minor as recommended in the manpage. So, by default it *is* what I want to use. Can you explain in more detail what the conditions are that would cause /dev/temp to not be what I want? The only possibility I can see is if there's another driver that I could load that would also use the same major/minor but would provide an incompatible interface. In that case I can understand why you might be using the device name to differentiate, but that would only work if you're relying on a udev environment that only exposes /dev entries if the right driver is there. In other words, if /dev/temperature is there and the wrong driver gets loaded, /dev/temperature will also be providing the wrong interface. If that's the case, it seems like the *right* answer is to make udev create something like your suggested /dev/nwtemp with a unique major/minor. I don't see how a symlink is of any value - by doing a symlink we're assuming /dev/temp is correct. But if its correct, why not use it directly? -- dann frazier | HP Open Source and Linux Organization -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
