System: NetBSD sugar 1.6F NetBSD 1.6F (SUGAR-$Revision: 1.465 $) #50: Tue Apr 1 16:32:22 JST 2003 root@sugar:/usr/src/sys/arch/i386/compile/SUGAR i386
In INTRO(2), pathname is defined as follows.
> A path name is a NUL-terminated character string starting with an
> optional slash `/', followed by zero or more directory names sep-
> arated by slashes, optionally followed by a file name. The total
> length of a path name must be less than 1024 (MAXPATHLEN) charac-
> If a path name begins with a slash, the path search begins at the
> root directory. Otherwise, the search begins from the current
> working directory. A slash by itself names the root directory.
> An empty pathname refers to the current directory.
But for POSIX conformance, NetBSD namei(9) implementation had
Empty pathname is treated as a illegal pathname(ENOENT),
as mentiond in vfs_lookup.c comment.

- An empty pathname refers to the current directory.
