After reloading Synaptic earlier today I discovered that I have a package named 'audit' which should be updated. If it is updated two other packages have to be installed.
This is what Synaptic says about the package:
User-space tools for Linux 2.6 kernel auditing
The audit package contains the user space utilities for storing and searching
the audit records generate by the audit subsystem in the Linux 2.6 kernel.
The kernel I am using is 3.2.18-pclos2.bfs.
Synaptic will allow me to remove the package but I have held off in case I shouldn't. I installed from the 2012.08 mini iso and have not deliberately installed audit.
Do I need it?
