From time to time, someone sends patches about unlinking existing sockets when registering a vhost user in server mode. A recent example: http://dpdk.org/ml/archives/dev/2018-February/090025.html This problem has been discussed many times, and it was made clear that the library should not unlink files given by the application in order to avoid possible security problems, such as removing random files used by other programs. One of the first discussions: http://dpdk.org/ml/archives/dev/2015-December/030326.html To avoid such patches in the future, it was decided to add a comment that explains what is happening and tries to describe the reasoning.
