I was hoping you wouldn't say that.  Murphy was telling me you would.

Mike commented that both the old and new methods should be working ...
I agree, at least until the new method doesn't resemble keystone kops so
well.

Bruce hasn't replied yet, let's be patient.  I at least don't know
enough about it to undo anything he's done.  I *could* do that, but not
with safety.

OK.  Can the field in struct statfs, f_fsid, be mapped to something,
like say the struct vfsconf that comes back from a getvfsbyname(), the
vfc_typenum field?

Geeze, that nfs code is impenetrable.
