how to execute a script from NFS mount (which disconnected)?

[Tomasz Chmielewski <mangoo@wpkg.org>]

This question may sound silly, but I didn't find a proper solution to it.

I have a script on a NFS share. The purpose of this script is to do some 
network reconfiguration for Xen.

Unfortunately, it fails to execute somewhere in the middle.

Basically, the script brings the network interface down, does a bit of 
reconfiguring, and then, the interface is brought up.


In a short form, the script looks like that:

#!/bin/bash

echo Start

ifdown bond0

echo Step 1...
sleep 4s

echo Step 2...
sleep 4s

echo Step 3...
sleep 4s

echo Step 4...
sleep 4s

echo Step 5...
sleep 4s

ifup bond0

echo End



Unfortunately, when I execute it locally, the script freezes somewhere 
about step 2 or 3. Which I could perfectly understand - as the system 
can't read it.
But I did a "cat script" just before running it - so the system should 
have it cached, right?
Sometimes only, the script executes fully.


How can I execute a script from NSF mount - a script which reconfigures 
a network interface, and there is a period of network disconnection?
