Hi, Maxim:
Thank you very much ! I think b) is good reason, a) is pretty weak:
The /the/path/to/unix/domain/socket is a constant string instead of a
variable; IMHO, it's unlikely to accidentally delete a wrong file due to
typo.
Thanks

Is there any reason not to delete UNIX domain socket before bind?
To name a few, deleting a socket implies that:
a) any file can be accidentally deleted due to a typo in the
listen directive;
b) attempts to do duplicate listen are not detected and silently
break service, e.g., if you start duplicate instance of nginx.
Instead we delete the socket after closing it.
