] Assume a very computer system from a company that used a very old legacy device whose path is /dev/legacy/specialdevice and it is about to be decomissioned. However, there are several important pieces of software who use this legacy device to log their output and you cannot change those. That means, the path /dev/legacy/specialdevice must continue to exist although the underlying physical device must be replaced. Now, what can you do to make sure all legacy tools and software continues running w/o problem without putting a new physical device in the above path? Note: you may forward all traffic to the legacy device to let’s say /sys/logfile path
