freeBSD nullfs together nfs and "silly rename"

[Leon Meßner]

Hi,

when you try to do the following inside a nullfs mounted directory,
where the nullfs origin is itself mounted with nfs you get an error:

# foo 
# tail -f foo& 
# rm -f foo 
tail: foo: Stale NFS file handle
# fg


This is really a problem when running services inside jails and using
NFS as storage. As of [2] it looks like this problem is known for a
while. On a normal NFS mount this does not happen as "silly renaming"
[1] works there.

As freeBSD is getting towards NFSv4 perhaps this would be a solution but
i actually would'nt want to use these in production.
Is there a fix or anything ?
