After the program that listened on them exited they are useless and cannot be reused, they hence *must* be removed before another program can listen on them again. > The problem with sharing files between applications using /tmp is this > specification: > > http://www.pathname.com/fhs/pub/fhs-2.3.html#TMPTEMPORARYFILES > | Programs must not assume that any files or directories in /tmp are > | preserved between invocations of the program. > > So in case there will be a file system for /tmp that automatically > removes files once they are not open anymore, abusing /tmp for this > will fail. Uh? First of all, such an fs does not exist. Secondly, as mentioned a unix socket is useless in the fs after the program that listened on it exited, hence automatically deleting the unix socket as soon as it exited would actually be a good idea.
