Hi all, How does Linux determine what updates are available for a system, does it check the installed software and patches, or is this unique key generated and stored on the system? I illustrate with an example below: PC 1 = no internet connection, unable to be networked PC 2 = internet connection enabled, able to be networked All installed systems need to get updates from the internet, whether they be program or security updates. Is there a system value that is generated by PC 1 that would be unique to it? Could this value then be retrieved and put into a web page on PC 2 and all the updates for PC 1 could be downloaded and burnt to a CD. I would then like to use this burnt CD to update PC 1, as though it was connected to the internet. This update CD would include all the software and security patches that PC 1 requires. This CD would then update the system from its initial install or from the last time an update CD was used.
