/*
 * a batch_update file is structured as follows:
 *
 *	file header record
 *	dump_header record	"header.h"
 *	bu_name record
 *	ascii name
 *	bu_name record
 *	ascii name
 *	.
 *	.
 *	.
 *	dnode record		"dnode.h"
 *	dnode record
 *	.
 *	.
 *	.
 *	bu_tape record
 *	bu_tape record
 *	.
 *	.
 *	.
 *	file header record (duplicate of the one at the beginning)
 *
 * The name records occur in directory order, i.e., a directory
 * record (with type == 1) is immediately followed by all of the
 * records for its entries.  However, no hierarchical relationship
 * among directories can be inferred from the order of the entries.
 * The root directory is always assumed to
 * be the first name entry in the file (and/or inode number 2).
 *
 * XXX: note that the mount point in the dump header record is critical
 * for building correct path names.
