[Prabhu Ramachandran <prabhu@xxxxxxxxxxxxxxxxxx>]

Dear Sir,

	Here is what I do on my old machine where /usr, /usr/local are 
mounted read-only.

In root's .bashrc I have the following functions defined.

------------
function mrw
{
mount -o remount,rw $@
}

function mro
{
mount -o remount,ro $@
}
------------

	So all i do is this:

# mrw /usr
# apt-get update; apt-get upgrade
# mro /usr

It works fine.  The remount argument is the key.
