I have a bunch of remote computers that must be updated to the most recent packages for RedHat 4 and RedHat 5. I am using mrepo to mirror the RHN packages, however the remote computers do not have an internet connection. Because of this I have to update the mirror server that is part of the remote computers with a dvd. This is to cut down shipping costs to just a dvd. I am attempting to script this so I can fit all of the new packages on a CD or a DVD. I send updates about once or twice a month depending on package requirements. So my question is, is their a good method to do this so that the only things transferred are the new packages? I wish I could just use rsync. Thanks.
