The "exportfs" man page explains a little about the "legacy" vs "new"
modes of mountd/exportfs operation.

As I said, two things happened:
	1. The "nfsd" filesystem didn't get mounted under /proc/ as it's
	   suppose to be.
	2. The server therefore should have been using the "legacy" mode
	   of operation.  But it didn't work for some reason.

I'm not sure in either case.

If you do put an explicit nfsd mount in the fstab, then you won't see
this problem again.
