nfs barfs

i need to re-export an nfs mount because i need to. i do my usual /etc/exports editing. and then nfsd barfs...

root@server:~# exportfs -ra
exportfs: Warning: /my/export does not support NFS export.

why?

Of course...
/etc/default/nfs-kernel-server
needs this line...

REEXPORT_NFS="yes"
then re-start nfs services, statd junk and portmap.

root@server:~# exportfs -ra

no error. nice. or just install unfs3.
