After update my NFS server, I can't NFS mount via amd(8) any longer.
(though normal NFS mount via mount_nfs(8) works)
On the NFS server (with 3.99.22 kernel and 3.99.21 userland),
mountd(8) complains "mountd: Can't get fh for /r/export"
when NFS clients try to mount directories via amd(8).
According to ktrace(1), getfh(2) (compat version) fails with E2BIG.
Any idea? Do I have to update binaries?
