This is probably because NFS can't handle ``large'' major/minor numbers (my guess is that they are truncated down to 8 bits for encoding into the structure passed back and forth).

(You have to remember that NFS v2 came about BEFORE people started needing lots of these ``new'' features, and it can't cope ... ) Gary -- Gary Palmer FreeBSD Core Team Member FreeBSD: Turning PC's into workstations.
