60 * ROOTID and SLINKID are the fixed "faked" node IDs (inodes) for
61 * the '.' (also '..') and the one symlink within the hlfs.
62 * They must always be unique, and should never match what a UID
64 * They used to be -1 and -2, respectively.
66 * I used to cast these to (uid_t) but it failed to compile
67 * with /opt/SUNWspro/bin/cc because uid_t is long, while struct fattr's
68 * uid field is u_int. Then it failed to compile on some linux systems
69 * which define uid_t to be unsigned short, so I used the lowest common
70 * size which is unsigned short.
73 * XXX: this will cause problems to systems with UIDs greater than
74 * MAX_UNSIGNED_SHORT-3.
