I've set up the NFSv4 server, which seems to be supporting flags, but, 
unfortunately, due to the design of the NFSv4 stub /usr is not exported 
at all.

I've also tried to use the nullfs, but it dislikes the /:

# mount -t nullfs / /mnt/usr
mount_nullfs: / (/) and /mnt/usr are not distinct paths

Are there any chance to get to the stub /usr without singlebooting using 
the console ?

Thanks.

Eugene.
