[src/trunk]: src Nodes cannot use the '0' identifier or they will be skipped ...

[jmmv <jmmv%NetBSD.org@localhost>]

details:   https://anonhg.NetBSD.org/src/rev/bc8c40112bf7
branches:  trunk
changeset: 584343:bc8c40112bf7
user:      jmmv <jmmv%NetBSD.org@localhost>
date:      Tue Sep 13 21:30:52 2005 +0000

description:
Nodes cannot use the '0' identifier or they will be skipped by readdir.
E.g., the root node's '.' and '..' directory entries did not appear in
a directory list, because the root node always holds the first id.
