freebsd stable - Mar 2009 - ZFS and NFS: changing handles between reboots

Dear colleagues,

is it normal that between reboots NFS exported ZFS file systems change NFS 
handles? After server reboot, I have

stale NFS handle

on any request to previously mounted FS. On UFS, mounted NFS file systems 
survive server reboots...

Thanks in advance.

Are you sure anout that ? I have a lot of systems sharing files using UFS
and I see the 'stale NFS file handle' thing if I reboot the server too.
No ZFS involved there.
