This is one possibility indeed. The good thing is that libsensors makes no assumption on hwmon class device names, so we can change the names without breaking any application which uses libsensors. Scripts accessing sysfs directly may break though (pwmconfig would, for example.) We'll have to be careful when choosing the new names, and make sure there is no name space collision. Network interface renaming has caused a great deal of trouble out there. Another approach, which I have in mind for quite some time already but could never find the time to implement, would be a small helper binary which would look-up hwmon devices by libsensors-like name (and the other way around too.) Scripts could use it to benefit from libsensors persistent names. -- Jean Delvare SUSE L3 Support
