No, not really. According to Documentation/ABI/testing/sysfs-class all code that uses /sys/class/foo/ needs to be able to handle the fact that those entries might be symlinks and not just directories. Everything that I know of already works properly because the input layer has had symlinks in /sys/class/input for quite some time now. Do you know of any tools that use /sys/class/net/ that can not handle symlinks there? I've been running this on my boxes for about a week now with no noticeable issues. Renaming interfaces works just fine too. thanks, greg k-h
