Right, the problem is NetBSD’s file handles have this little guy at the front:
typedef struct { int32_t __fsid_val[2]; } fsid_t; /* file system id type */
In a perfect world, each file system would have a UUID and the file handle
would pack the UUID in front of the file ID rather than this fsid_t thing
(which is really just container for a dev_t).
