-         slash, and POSIX requires that the unlink attempt to remove
-         that directory (which would leave the symlink dangling).
-         Unfortunately, Solaris 9 is one of the platforms where the
-         root user can unlink directories, and we don't want to
-         cripple this behavior on real directories, even if it is
-         seldom needed (at any rate, it's nicer to let coreutils'
-         unlink(1) give the correct errno for non-root users).  But we
-         don't know whether name was an actual directory, or a symlink
-         to a directory; and due to the bug of ignoring trailing
-         slash, Solaris 9 would end up successfully unlinking the
-         symlink instead of the directory.  Technically, we could use
-         realpath to find the canonical directory name to attempt
-         deletion on.  But that is a lot of work for a corner case; so
-         we instead just use an lstat on the shortened name, and
-         reject symlinks with trailing slashes.  The root user of
-         unlink(1) will just have to live with the rule that they
-         can't delete a directory via a symlink.  */
