Yes, I am aware that NFS mounts do not work well
with VNET jails. Unless someone conversant with VNET
jails comes up with a patch, it won't be fixed anytime soon.

I think one problem (probably not the only one) happens
when the NFS client needs to re-connect to the server.
The code needs to do a soconnect() and assorted other
calls. These are only allowed if in the correct VNET jail,
but the NFS client code does not know what that is.
--> reconnect fails and mountpoint is dead.

However, I do not know how using an NFS mount with a
VNET jail will produce the "..BROKEN MIDDLEWARE.."
